Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Financial Statements	INTERIM FINANCIAL STATEMENTS Business and Basis of Presentation AutoNation, Inc., through its subsidiaries, is one of the largest automotive retailers in the United States. As of September 30, 2022, we owned and operated 336 new vehicle franchises from 243 stores located in the United States, predominantly in major metropolitan markets in the Sunbelt region. Our stores, which we believe include some of the most recognizable and well-known in our key markets, sell 33 different new vehicle brands. The core brands of new vehicles that we sell, representing approximately 89% of the new vehicles that we sold during the nine months ended September 30, 2022, are manufactured by Toyota (including Lexus), Ford, Honda, Mercedes-Benz, BMW, General Motors, Stellantis, and Volkswagen (including Audi and Porsche). As of September 30, 2022, we also owned and operated 56 AutoNation-branded collision centers, 12 AutoNation USA used vehicle stores, 4 AutoNation-branded automotive auction operations, and 3 parts distribution centers. We offer a diversified range of automotive products and services, including new vehicles, used vehicles, “parts and service” (also referred to as “After-Sales”), which includes automotive repair and maintenance services as well as wholesale parts and collision businesses, and automotive “finance and insurance” products, which include vehicle service and other protection products, as well as the arranging of financing for vehicle purchases through third-party finance sources. For convenience, the terms “AutoNation,” “Company,” and “we” are used to refer collectively to AutoNation, Inc. and its subsidiaries, unless otherwise required by the context. Our dealership operations are conducted by our subsidiaries. The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of AutoNation, Inc. and its subsidiaries; intercompany accounts and transactions have been eliminated. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year. The Unaudited Condensed Consolidated Financial Statements herein should be read in conjunction with our audited Consolidated Financial Statements and notes thereto included within our most recent Annual Report on Form 10-K. These Unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all material adjustments (which include only normal recurring adjustments) necessary to fairly state, in all material respects, our financial position and results of operations for the periods presented.

Revenue Recognition [Abstract]
Revenue Recognition	REVENUE RECOGNITION Disaggregation of Revenue The significant majority of our revenue is from contracts with customers. Taxes assessed by governmental authorities that are directly imposed on revenue transactions are excluded from revenue. In the following tables, revenue is disaggregated by major lines of goods and services and timing of transfer of goods and services.

Transaction Price Allocated to Remaining Performance Obligations We sell a vehicle maintenance program (the AutoNation Vehicle Care Program or “VCP”) under which a customer purchases a specific number of maintenance services to be redeemed at an AutoNation location over a five-year term from the date of purchase. We satisfy our performance obligations related to this program and recognize revenue as the maintenance services are rendered, since the customer benefits when we have completed the maintenance service. The following table includes estimated revenue expected to be recognized in the future related to VCP performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period: Revenue Expected to Be Recognized by Period Total Next 12 Months 13 - 36 Months 37 - 60 Months Revenue expected to be recognized on VCP contracts sold as of period end $ 99.9 $ 34.4 $ 47.6 $ 17.9 As a practical expedient, since automotive repair and maintenance services are performed within one year or less, we do not disclose estimated revenue expected to be recognized in the future for automotive repair and maintenance performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period or when we expect to recognize such revenue. Contract Assets and Liabilities When the timing of our provision of goods or services is different from the timing of payments made by our customers, we recognize either a contract asset (performance precedes contractual due date) or a contract liability (customer payment precedes performance). Contract assets primarily relate to our right to consideration for work in process not yet billed at the reporting date associated with automotive repair and maintenance services, as well as our estimate of variable consideration that has been included in the transaction price for certain finance and insurance products (retrospective commissions). These contract assets are reclassified to receivables when the right to consideration becomes unconditional. Contract liabilities primarily relate to upfront payments received from customers for the sale of VCP contracts. Our receivables from contracts with customers are included in Receivables, net, our current contract asset is included in Other Current Assets, our long-term contract asset is included in Other Assets, our current contract liability is included in Other Current Liabilities, and our long-term contract liability is included in Other Liabilities in our Unaudited Condensed Consolidated Balance Sheets.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period, including vested restricted stock unit (“RSU”) awards. Diluted EPS is computed by dividing net income by the weighted average number of shares outstanding, noted above, adjusted for the dilutive effect of unvested RSU awards and stock options. The following table presents the calculation of basic and diluted EPS: Three Months Ended Nine Months Ended September 30, September 30, 2022 2021 2022 2021 Net income from continuing operations $ 352.7 $ 361.7 $ 1,091.3 $ 986.1 Loss from discontinued operations, net of income taxes (0.1) — (0.3) (0.2) Net income $ 352.6 $ 361.7 $ 1,091.0 $ 985.9 Basic weighted average common shares outstanding 55.5 69.9 58.5 77.3 Dilutive effect of unvested RSUs and stock options 0.4 0.8 0.4 0.8 Diluted weighted average common shares outstanding 55.9 70.7 58.9 78.1 Basic EPS amounts (1) : Continuing operations $ 6.35 $ 5.17 $ 18.65 $ 12.76 Discontinued operations $ — $ — $ (0.01) $ — Net income $ 6.35 $ 5.17 $ 18.65 $ 12.75 Diluted EPS amounts (1) : Continuing operations $ 6.31 $ 5.12 $ 18.53 $ 12.63 Discontinued operations $ — $ — $ (0.01) $ — Net income $ 6.31 $ 5.12 $ 18.52 $ 12.62 (1) EPS amounts are calculated discretely and, therefore, may not add up to the total due to rounding.

Vehicle floorplan payable-non-trade represents amounts borrowed to finance the purchase of specific new and, to a lesser extent, used vehicle inventories with non-trade lenders, as well as amounts borrowed under our secured used vehicle floorplan facilities. Changes in vehicle floorplan payable-trade are reported as operating cash flows and changes in vehicle floorplan payable-non-trade are reported as financing cash flows in the accompanying Unaudited Condensed Consolidated Statements of Cash Flows. Our inventory costs are generally reduced by manufacturer holdbacks, incentives, floorplan assistance, and non-reimbursement-based manufacturer advertising rebates, while the related vehicle floorplan payables are reflective of the gross cost of the vehicle. The vehicle floorplan payables, as shown in the above table, may also be higher than the inventory cost due to the timing of the sale of a vehicle and payment of the related liability. Vehicle floorplan facilities are due on demand, but in the case of new vehicle inventories, are generally paid within several business days after the related vehicles are sold. Vehicle floorplan facilities are primarily collateralized by vehicle inventories and related receivables. At September 30, 2022, most of our new vehicle floorplan facilities utilized LIBOR-based interest rates and a smaller portion utilized Prime-based or SOFR-based interest rates. Our new vehicle floorplan outstanding had a weighted-average interest rate of 4.7% at September 30, 2022, and 1.6% at December 31, 2021. As of September 30, 2022, the aggregate capacity under our new vehicle floorplan facilities to finance our new vehicle inventory was approximately $4.7 billion, of which $1.1 billion had been borrowed.

The interest rates payable on our 3.5% Senior Notes, 4.5% Senior Notes, 3.8% Senior Notes, and 4.75% Senior Notes are subject to adjustment upon the occurrence of certain credit rating events as provided in the indentures for these senior unsecured notes. Under our amended and restated credit agreement, we have a $1.8 billion revolving credit facility that matures on March 26, 2025. The credit agreement also contains an accordion feature that allows us, subject to credit availability and certain other conditions, to increase the amount of the revolving credit facility, together with any added term loans, by up to $500.0 million in the aggregate. As of September 30, 2022, we had no borrowings outstanding under our revolving credit facility. We have a $200.0 million letter of credit sublimit as part of our revolving credit facility. The amount available to be borrowed under the revolving credit facility is reduced on a dollar-for-dollar basis by the cumulative amount of any outstanding letters of credit, which was $39.8 million at September 30, 2022, leaving a borrowing capacity under the revolving credit facility of $1.8 billion at September 30, 2022. In September 2022, we made certain administrative amendments to our credit agreement, including the replacement of the reference rate from LIBOR to Term SOFR (“SOFR”) in connection with global reference rate reform initiatives. This modification will be accounted for by prospectively adjusting the effective interest rate in accordance with accounting standards. We do not expect the change from LIBOR to SOFR to have a material impact on our annual interest expense. Our revolving credit facility under the amended credit agreement provides for a commitment fee on undrawn amounts ranging from 0.125% to 0.20% and interest on borrowings at SOFR plus a credit spread adjustment of 0.10% or the base rate, in each case plus an applicable margin. The applicable margin ranges from 1.125% to 1.50% for SOFR borrowings and 0.125% to 0.50% for base rate borrowings. The interest rate charged for our revolving credit facility is affected by our leverage ratio. Within the meaning of Regulation S-X, Rule 3-10, AutoNation, Inc. (the parent company) has no independent assets or operations. If guarantees of our subsidiaries were to be issued under our existing registration statement, we expect that such guarantees would be full and unconditional and joint and several, and any subsidiaries other than the guarantor subsidiaries would be minor. Other Long-Term Debt At September 30, 2022, we had finance leases and other debt obligations of $321.6 million, which are due at various dates through 2041. Commercial Paper We have a commercial paper program pursuant to which we may issue short-term, unsecured commercial paper notes on a private placement basis up to a maximum aggregate amount outstanding at any time of $1.0 billion. The interest rate for the commercial paper notes varies based on duration and market conditions. The maturities of the commercial paper notes may vary, but may not exceed 397 days from the date of issuance. Proceeds from the issuance of commercial paper notes are used to repay borrowings under the revolving credit facility, to finance acquisitions, and for strategic initiatives, working capital, capital expenditures, share repurchases, and/or other general corporate purposes. We plan to use the revolving credit facility under our credit agreement as a liquidity backstop for borrowings under the commercial paper program. A downgrade in our credit ratings could negatively impact our ability to issue, or the interest rates for, commercial paper notes.

Currently, no tax years are under examination by the IRS, and tax years from 2014 to 2019 are under examination by certain U.S. state jurisdictions. These audits may result in proposed assessments where the ultimate resolution may result in our owing additional taxes. It is our policy to account for interest and penalties associated with income tax obligations as a component of Income Tax Provision in the accompanying Unaudited Condensed Consolidated Statements of Operations.

In October 2022, our Board of Directors increased the share repurchase authorization by $1.0 billion. Our Board of Directors authorized the retirement of 16.0 million shares of our treasury stock in April 2021, which assumed the status of authorized but unissued shares. Upon the retirement of treasury stock, it is our policy to charge the excess of the cost of the treasury stock over its par value entirely to additional paid-in capital. Any amounts exceeding additional paid-in capital are charged to retained earnings. This retirement had the effect of reducing treasury stock and issued common stock, which includes treasury stock. Our common stock, additional paid-in capital, retained earnings, and treasury stock accounts were adjusted accordingly. There was no impact to shareholders’ equity or outstanding common stock. We have 5.0 million authorized shares of preferred stock, par value $0.01 per share, none of which are issued or outstanding. The Board of Directors has the authority to issue the preferred stock in one or more series and to establish the rights, preferences, and dividends of such preferred stock.

Financial Instruments And Fair Value Measurements	Sep. 30, 2022
Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. Fair value estimates are made at a specific point in time based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of judgment, and therefore cannot be determined with precision. Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value: Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities that a reporting entity can access at the measurement date Level 2 Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly Level 3 Unobservable inputs The following methods and assumptions were used by us in estimating fair value disclosures for financial instruments: • Cash and cash equivalents, receivables, other current assets, vehicle floorplan payable, accounts payable, other current liabilities, commercial paper, and variable rate debt : The amounts reported in the accompanying Unaudited Condensed Consolidated Balance Sheets approximate fair value due to their short-term nature or the existence of variable interest rates that approximate prevailing market rates. • Investments in Equity Securities: Our equity investments with readily determinable fair values are measured at fair value using Level 1 inputs. In the first quarter of 2021, we sold one of our minority equity investments with a readily determinable fair value for total proceeds of $109.4 million. The fair value of our equity investments with readily determinable fair values totaled $2.1 million at September 30, 2022 and $2.2 million at December 31, 2021. Our equity investment that does not have a readily determinable fair value is measured using the measurement alternative as permitted by accounting standards and was recorded at cost, to be subsequently adjusted for observable price changes. The carrying amount of our equity investment without a readily determinable fair value was $56.7 million at September 30, 2022, and $56.7 million at December 31, 2021. This equity investment reflects a cumulative upward adjustment of $3.4 million based on an observable price change. We did not record any upward adjustments during the nine months ended September 30, 2022. Additionally, we have not recorded any impairments or downward adjustments to the carrying amount of our equity investment as of and for the nine months ended September 30, 2022. Investments in equity securities are reported in Other Assets in the accompanying Unaudited Condensed Consolidated Balance Sheets. Realized and unrealized gains and losses are reported in Other Income (Loss), Net (non-operating) in the Unaudited Condensed Consolidated Statements of Operations and in the “Corporate and other” category of our segment information. Nine Months Ended September 30, 2022 2021 Net gains (losses) recognized during the period on equity securities $ (0.1) $ 10.9 Less: Net gains recognized during the period on equity securities sold during the period — 7.5 Unrealized gains (losses) recognized during the reporting period on equity securities still held at the reporting date $ (0.1) $ 3.4 • Fixed rate long-term debt : Our fixed rate long-term debt primarily consists of amounts outstanding under our senior unsecured notes. We estimate the fair value of our senior unsecured notes using quoted prices for the identical liability (Level 1). A summary of the aggregate carrying values and fair values of our fixed rate long-term debt is as follows: September 30, December 31, Carrying value $ 3,544.6 $ 2,858.4 Fair value $ 3,095.6 $ 3,017.8 Nonfinancial assets such as goodwill, other intangible assets, long-lived assets held and used, and right-of-use assets are measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized or for a business combination. The fair values less costs to sell of long-lived assets held for sale are assessed each reporting period they remain classified as held for sale. Subsequent changes in the held for sale long-lived asset’s fair value less cost to sell (increase or decrease) is reported as an adjustment to its carrying amount, except that the adjusted carrying amount cannot exceed the carrying amount of the long-lived asset at the time it was initially classified as held for sale. The following table presents assets measured and recorded at fair value on a nonrecurring basis during the nine months ended September 30, 2022 and 2021: 2022 2021 Description Fair Value Gain/(Loss) Fair Value Gain/(Loss) Equity investment $ — $ — $ 53.4 $ 3.4 Right-of-use assets $ — $ — $ — $ (0.1) Long-lived assets held and used $ — $ (1.0) $ 10.4 $ (3.1) Goodwill and Other Intangible Assets Goodwill for our reporting units and our franchise rights assets are tested for impairment annually as of April 30 or more frequently when events or changes in circumstances indicate that impairment may exist. Under accounting standards, we chose to make a qualitative evaluation about the likelihood of goodwill impairment for our annual impairment testing as of April 30, 2022 and 2021, and we determined that it was not more likely than not that the fair values of our reporting units were less than their carrying amounts. Our principal identifiable intangible assets are individual store rights under franchise agreements with vehicle manufacturers, which have indefinite lives and are tested for impairment annually as of April 30 or more frequently when events or changes in circumstances indicate that impairment may have occurred. We elected to perform quantitative franchise rights impairment tests as of April 30, 2022 and 2021, and no impairment charges resulted from these quantitative tests. The quantitative impairment test for franchise rights requires the comparison of the franchise rights’ estimated fair value to carrying value by store. Fair values of rights under franchise agreements are estimated using Level 3 inputs by discounting expected future cash flows of the store. The forecasted cash flows contain inherent uncertainties, including significant estimates and assumptions related to growth rates, margins, working capital requirements, capital expenditures, and cost of capital, for which we utilize certain market participant-based assumptions, using third-party industry projections, economic projections, and other marketplace data we believe to be reasonable. Long-Lived Assets and Right-of-Use Assets Fair value measurements for our long-lived assets and right-of-use assets are based on Level 3 inputs. Changes in fair value measurements are reviewed and assessed each quarter for long-lived assets classified as held for sale, or when an indicator of impairment exists for long-lived assets classified as held and used or for right-of-use assets. The valuation process is generally based on a combination of the market and replacement cost approaches. In a market approach, we use transaction prices for comparable properties that have recently been sold. These transaction prices are adjusted for factors related to a specific property. We evaluate changes in local real estate markets, and/or recent market interest or negotiations related to a specific property. In a replacement cost approach, the cost to replace a specific long-lived asset is considered, which is adjusted for depreciation from physical deterioration, as well as functional and economic obsolescence, if present and measurable. To validate the fair values determined under the valuation process noted above, we also obtain independent third-party appraisals for our properties and/or third-party brokers’ opinions of value, which are generally developed using the same valuation approaches described above, and we evaluate any recent negotiations or discussions with third-party real estate brokers related to a specific long-lived asset or market. The non-cash impairment charges related to right-of-use assets and long-lived assets held and used are included in Other Income, Net in our Unaudited Condensed Consolidated Statements of Operations and in the “Corporate and other” category of our segment information. We had assets held for sale in continuing operations of $8.4 million as of September 30, 2022, and $53.3 million as of December 31, 2021 related to property held for sale. We had assets held for sale in discontinued operations of $1.1 million as of

Commitments And Contingencies	Sep. 30, 2022
Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Legal Proceedings We are involved, and will continue to be involved, in numerous legal proceedings arising out of the conduct of our business, including litigation with customers, wage and hour and other employment-related lawsuits, and actions brought by governmental authorities. Some of these lawsuits purport or may be determined to be class or collective actions and seek substantial damages or injunctive relief, or both, and some may remain unresolved for several years. We establish accruals for specific legal proceedings when it is considered probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Our accruals for loss contingencies are reviewed quarterly and adjusted as additional information becomes available. We disclose the amount accrued if material or if such disclosure is necessary for our financial statements to not be misleading. If a loss is not both probable and reasonably estimable, or if an exposure to loss exists in excess of the amount accrued, we assess whether there is at least a reasonable possibility that a loss, or additional loss, may have been incurred. If there is a reasonable possibility that a loss, or additional loss, may have been incurred, we disclose the estimate of the possible loss or range of loss if it is material or a statement that such an estimate cannot be made. Our evaluation of whether a loss is reasonably possible or probable is based on our assessment and consultation with legal counsel regarding the ultimate outcome of the matter. As of September 30, 2022 and 2021, we have accrued for the potential impact of loss contingencies that are probable and reasonably estimable, and there was no indication of a reasonable possibility that a material loss, or additional material loss, may have been incurred. We do not believe that the ultimate resolution of these matters will have a material adverse effect on our results of operations, financial condition, or cash flows. However, the results of these matters cannot be predicted with certainty, and an unfavorable resolution of one or more of these matters could have a material adverse effect on our results of operations, financial condition, or cash flows. Other Matters AutoNation, acting through its subsidiaries, is the lessee under many real estate leases that provide for the use by our subsidiaries of their respective store premises. Pursuant to these leases, our subsidiaries generally agree to indemnify the lessor and other related parties from certain liabilities arising as a result of the use of the leased premises, including environmental liabilities, or a breach of the lease by the lessee. Additionally, from time to time, we enter into agreements with third parties in connection with the sale of assets or businesses in which we agree to indemnify the purchaser or related parties from certain liabilities or costs arising in connection with the assets or business. Also, in the ordinary course of business in connection with purchases or sales of goods and services, we enter into agreements that may contain indemnification provisions. In the event that an indemnification claim is asserted, our liability would be limited by the terms of the applicable agreement. From time to time, primarily in connection with dispositions of automotive stores, our subsidiaries assign or sublet to the store purchaser the subsidiaries’ interests in any real property leases associated with such stores. In general, our subsidiaries retain responsibility for the performance of certain obligations under such leases to the extent that the assignee or sublessee does not perform, whether such performance is required prior to or following the assignment or subletting of the lease. Additionally, AutoNation and its subsidiaries generally remain subject to the terms of any guarantees made by us and our subsidiaries in connection with such leases. Although we generally have indemnification rights against the assignee or sublessee in the event of non-performance under these leases, as well as certain defenses, we estimate that lessee rental payment obligations during the remaining terms of these leases with expirations ranging from 2022 to 2034 are approximately $7 million at September 30, 2022. We do not have any material known commitments that we or our subsidiaries will be called on to perform under any such assigned leases or subleases at September 30, 2022. There can be no assurance that any performance by AutoNation or its subsidiaries required under these leases would not have a material adverse effect on our business, financial condition, and cash flows. At September 30, 2022, surety bonds, letters of credit, and cash deposits totaled $105.4 million, of which $39.8 million were letters of credit. In the ordinary course of business, we are required to post performance and surety bonds, letters of credit, and/or cash deposits as financial guarantees of our performance. We do not currently provide cash collateral for outstanding letters of credit.

Business And Credit Concentrations	Sep. 30, 2022
Risks and Uncertainties [Abstract]
Business And Credit Concentrations	BUSINESS AND CREDIT CONCENTRATIONS We own and operate franchised automotive stores in the United States pursuant to franchise agreements with vehicle manufacturers. During the nine months ended September 30, 2022, approximately 62% of our total retail new vehicle unit sales was generated by our stores in Florida, Texas, and California. We are subject to a concentration of risk in the event of financial distress of or other adverse event related to a major vehicle manufacturer or related lender or supplier. The core brands of vehicles that we sell, representing approximately 89% of the new vehicles sold during the nine months ended September 30, 2022, are manufactured by Toyota (including Lexus), Ford, Honda, Mercedes-Benz, BMW, General Motors, Stellantis, and Volkswagen (including Audi and Porsche). Our business could be materially adversely impacted by a bankruptcy of or other adverse event related to a major vehicle manufacturer or related lender or supplier. We had receivables from manufacturers or distributors of $157.4 million at September 30, 2022, and $148.4 million at December 31, 2021. Additionally, a large portion of our contracts-in-transit included in Receivables, net, in the accompanying Unaudited Condensed Consolidated Balance Sheets, are due from automotive manufacturers’ captive finance subsidiaries, which provide financing directly to our new and used vehicle customers. Concentrations of credit risk with respect to non-manufacturer trade receivables are limited due to the wide variety of customers and markets in which our products are sold as well as their dispersion across many different geographic areas in the United States. Consequently, at September 30, 2022, we do not consider AutoNation to have any significant non-manufacturer concentrations of credit risk.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION At September 30, 2022 and 2021, we had three reportable segments: (1) Domestic, (2) Import, and (3) Premium Luxury. Our Domestic segment is comprised of retail automotive franchises that sell new vehicles manufactured by Ford, General Motors, and Stellantis. Our Import segment is comprised of retail automotive franchises that sell new vehicles manufactured primarily by Toyota, Honda, Hyundai, Subaru, and Nissan. Our Premium Luxury segment is comprised of retail automotive franchises that sell new vehicles manufactured primarily by Mercedes-Benz, BMW, Lexus, Audi, and Jaguar Land Rover. The franchises in each segment also sell used vehicles, parts and automotive repair and maintenance services, and automotive finance and insurance products. “Corporate and other” is comprised of our other businesses, including collision centers, AutoNation USA used vehicle stores, auction operations, and parts distribution centers, all of which generate revenues but do not meet the quantitative thresholds for reportable segments, as well as unallocated corporate overhead expenses and other income items. The reportable segments identified above are the business activities of the Company for which discrete financial information is available and for which operating results are regularly reviewed by our chief operating decision maker to allocate resources and assess performance. Our chief operating decision maker is our Chief Executive Officer.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of AutoNation, Inc. and its subsidiaries; intercompany accounts and transactions have been eliminated. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year. The Unaudited Condensed Consolidated Financial Statements herein should be read in conjunction with our audited Consolidated Financial Statements and notes thereto included within our most recent Annual Report on Form 10-K. These Unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all material adjustments (which include only normal recurring adjustments) necessary to fairly state, in all material respects, our financial position and results of operations for the periods presented.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. We base our estimates and judgments on historical experience and other assumptions that we believe are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. We periodically evaluate estimates and assumptions used in the preparation of the financial statements and make changes on a prospective basis when adjustments are necessary. Such estimates and assumptions affect, among other things, our goodwill, indefinite-lived intangible asset, and long-lived asset valuations; inventory valuation; equity investment valuation; assets held for sale; assessments of variable consideration and related constraints related to retrospective commissions; accruals for chargebacks against revenue recognized from the sale of finance and insurance products; accruals related to self-insurance programs; certain legal proceedings; assessment of the annual income tax expense; valuation of deferred income taxes and income tax contingencies; the allowance for expected credit losses; and measurement of performance-based compensation costs.
Earnings Per Share	Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period, including vested restricted stock unit (“RSU”) awards. Diluted EPS is computed by dividing net income by the weighted average number of shares outstanding, noted above, adjusted for the dilutive effect of unvested RSU awards and stock options.
Impairment of Long-Lived Assets	Nonfinancial assets such as goodwill, other intangible assets, long-lived assets held and used, and right-of-use assets are measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized or for a business combination. The fair values less costs to sell of long-lived assets held for sale are assessed each reporting period they remain classified as held for sale. Subsequent changes in the held for sale long-lived asset’s fair value less cost to sell (increase or decrease) is reported as an adjustment to its carrying amount, except that the adjusted carrying amount cannot exceed the carrying amount of the long-lived asset at the time it was initially classified as held for sale.
