Organization, Consolidation and Presentation of Financial Statements [Abstract]
INTERIM FINANCIAL INFORMATION	INTERIM FINANCIAL INFORMATION Business Group 1 Automotive, Inc., a Delaware corporation, is a leading operator in the automotive retailing industry with business activities in 15 states in the U.S., 33 towns in the U.K. and three states in Brazil. Group 1 Automotive, Inc. and its subsidiaries are collectively referred to as the “Company” in these Notes to Condensed Consolidated Financial Statements. Through its dealerships, the Company sells new and used cars and light trucks; arranges related vehicle financing; sells service and insurance contracts; provides automotive maintenance and repair services; and sells vehicle parts. As of March 31, 2021, the Company’s retail network consisted of 118 dealerships in the U.S., 49 dealerships in the U.K. and 16 dealerships in Brazil. The U.S. and Brazil are led by the President, U.S. and Brazilian Operations, and the U.K. is led by an Operations Director, each reporting directly to the Company's Chief Executive Officer. The President, U.S. and Brazilian Operations, and the U.K. Operations Director are responsible for the overall performance of their respective regions, as well as for overseeing field level management. The Company’s operating results are generally subject to seasonal variations, as well as changes in the economic environment. In the U.S., the Company generally experiences higher volumes of vehicle sales and service in the second and third calendar quarters of each year. In addition, in some regions of the U.S., vehicle purchases decline during the winter months due to inclement weather. In the U.K., the first and third quarters tend to be stronger, driven by the vehicle license plate change months of March and September. In Brazil, the first quarter is generally the weakest, driven by more consumer vacations and activities associated with Carnival, while the third and fourth quarters tend to be stronger. Other factors unrelated to seasonality, such as the COVID-19 pandemic, changes in economic conditions, manufacturer incentive programs, supply issues, seasonal weather events and/or changes in currency exchange rates may exaggerate seasonal or cause counter-seasonal fluctuations in the Company’s revenues and operating income. Basis of Presentation The accompanying Condensed Consolidated Financial Statements and notes thereto, have been prepared in accordance with U.S. GAAP for interim financial information and in accordance with the rules and regulations of the SEC. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. Results for interim periods are not necessarily indicative of the results that can be expected for a full year and therefore should be read in conjunction with the Company’s audited Financial Statements and notes thereto included within the Company’s most recent Annual Report on Form 10-K. The accompanying Condensed Consolidated Financial Statements reflect the consolidated accounts of the parent company, Group 1 Automotive, Inc., and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been eliminated in consolidation. Certain prior-period amounts have been reclassified to conform to current-period presentation. Specifically, the long-term liabilities associated with the Company’s interest rate swaps have been combined into the caption Other long-term liabilities in the Condensed Consolidated Balance Sheets. The reclassification within the Condensed Consolidated Balance Sheets had no effect on any subtotal in the statements. Additionally, repayments and borrowings on the Company’s real estate related and other debt have been combined within the captions Repayments on other debt and Borrowings on other debt , respectively, in the Condensed Consolidated Statements of Cash Flows. The reclassification within the Condensed Consolidated Statements of Cash Flows had no effect on any subtotal in the statements. Certain amounts in the Condensed Consolidated Financial Statements and the accompanying notes may not compute due to rounding. All computations have been calculated using unrounded amounts for all periods presented. These Condensed Consolidated Financial Statements reflect, in the opinion of management, all normal recurring adjustments necessary to fairly state, in all material respects, the Company’s financial position and results of operations for the periods presented. Use of Estimates The preparation of the Company’s financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date and the amounts of revenues and expenses recognized during the reporting period. Management analyzes the Company’s estimates based on historical experience and other assumptions that are believed to be reasonable under the circumstances, however, actual results could differ materially from such estimates. The significant estimates made by management in the accompanying Condensed Consolidated Financial Statements include, but are not limited to, inventory valuation adjustments, reserves for future chargebacks on finance, insurance and vehicle service contract fees, self-insured property and casualty insurance exposure, the fair value of assets acquired and liabilities assumed in business combinations, the valuation of goodwill and intangible franchise rights and reserves for potential litigation.

SEGMENT INFORMATION	SEGMENT INFORMATION As of March 31, 2021 and 2020, the Company had three reportable segments: the U.S., U.K. and Brazil. The U.S. and Brazil segments are led by the President, U.S. and Brazilian Operations, and the U.K. segment is led by an Operations Director, each reporting directly to the Company's Chief Executive Officer, who is the CODM. The President, U.S. and Brazilian Operations, and the U.K. Operations Director are responsible for the overall performance of their respective regions, as well as for overseeing field level management.

Earnings Per Share [Abstract]
EARNINGS (LOSS) PER SHARE	EARNINGS (LOSS) PER SHARE The two-class method is utilized for the computation of the Company’s EPS. The two-class method requires a portion of net income to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends that are paid in cash. The Company’s RSAs are participating securities. Income allocated to these participating securities is excluded from net earnings available to common shares, as shown in the table below. Basic EPS is computed by dividing net income available to basic common shares by the weighted average number of basic common shares outstanding during the period. Diluted EPS is computed by dividing net income available to diluted common shares by the weighted average number of dilutive common shares outstanding during the period. The following table sets forth the calculation of EPS for the three months ended March 31, 2021 and 2020 (in millions, except share and per share data): Three Months Ended March 31, 2021 2020 Weighted average basic common shares outstanding 17,757,693 17,763,451 Dilutive effect of stock-based awards and employee stock purchases 66,396 44,810 Weighted average dilutive common shares outstanding 17,824,088 17,808,261 Basic: Net income (loss) $ 101.9 $ 29.8 Less: Earnings (loss) allocated to participating securities 3.5 1.1 Net income (loss) available to basic common shares $ 98.5 $ 28.7 Basic earnings (loss) per common share $ 5.54 $ 1.62 Diluted: Net income (loss) $ 101.9 $ 29.8 Less: Earnings (loss) allocated to participating securities 3.5 1.1 Net income (loss) available to diluted common shares $ 98.5 $ 28.7 Diluted earnings (loss) per common share $ 5.52 $ 1.61

FINANCIAL INSTRUMENTS AND FAIR

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS	3 Months Ended

Fair Value Disclosures [Abstract]
FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS	FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the most advantageous market in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy that 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 for identical assets or liabilities in active markets. • Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or model-derived valuations or other inputs that are observable or that can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Cash and Cash Equivalents, Contracts-In-Transit and Vehicle Receivables, Accounts and Notes Receivable, Accounts Payable, Variable Rate Long-Term Debt and Floorplan Notes Payable The fair values of these financial instruments approximate their carrying values due to the short-term nature of the instruments and/or the existence of variable interest rates. Demand Notes The Company periodically invests in demand notes with manufacturer-affiliated finance companies that bear interest at variable rates determined by the manufacturers and represent unsecured, unsubordinated and unguaranteed debt obligations of the manufacturers. The instruments are redeemable on demand by the Company and therefore the Company has classified these instruments as Cash and cash equivalents in the accompanying Condensed Consolidated Balance Sheets. As of March 31, 2021 and December 31, 2020, the carrying value of these instruments was $59.9 million and $60.0 million, respectively. The Company determined that the valuation measurement inputs of these instruments include inputs other than quoted market prices, that are observable or that can be corroborated by observable data by correlation. Accordingly, the Company has classified these instruments within Level 2 of the hierarchy framework. Fixed Rate Long-Term Debt The Company’s fixed rate long-term debt primarily consists of amounts outstanding under its senior unsecured notes and certain mortgage facilities. In August 2020, the Company issued $550.0 million in aggregate principal of 4.00% Senior Notes due August 2028 (“4.00% Senior Notes”). The Company estimates the fair value of its 4.00% Senior Notes using quoted prices for the identical liability (Level 1) and estimates the fair value of its fixed-rate mortgage facilities using a present value technique based on current market interest rates for similar types of financial instruments (Level 2). Refer to Note 9. Debt for further discussion of the Company’s long-term debt arrangements. The carrying value and fair value of the Company’s 4.00% Senior Notes and fixed rate mortgages were as follows (in millions): March 31, 2021 December 31, 2020 Carrying Value (1) Fair Value Carrying Value (1) Fair Value 4.00% Senior Notes $ 550.0 $ 545.6 $ 550.0 $ 567.0 Real estate related 82.6 74.2 84.3 77.0 Total $ 632.6 $ 619.7 $ 634.3 $ 644.0 (1) Carrying value excludes unamortized debt issuance costs. Derivative Financial Instruments The Company holds interest rate swaps to hedge against variability of interest payments indexed to LIBOR. The interest rate swaps are designated as cash flow hedges and the related gains or losses are deferred in stockholders’ equity as a component of Accumulated other comprehensive income (loss) . The deferred gains or losses are recognized in income in the period in which the related items being hedged are recognized in expense. Monthly contractual settlements of the positions are recognized as Floorplan interest expense or Other interest expense, net, in the Company’s Condensed Consolidated Statements of Operations. The Company had no gains or losses related to ineffectiveness recognized in the Condensed Consolidated Statements of Operations for the three months ended March 31, 2021 and 2020. As of March 31, 2021, the Company held 38 interest rate swaps in effect with a total notional value of $943.0 million that fixed its underlying one-month LIBOR at a weighted average rate of 1.48%. The Company also held 8 additional interest rate swaps with forward start dates beginning December 2021, that had an aggregate notional value of $425.0 million and a weighted average interest rate of 1.20% as of March 31, 2021. The maturity dates of the Company’s interest rate swaps with forward start dates range between January 2025 and December 2031. The Company’s interest rate swaps are measured at fair value utilizing the option-pricing Black-Scholes present value technique. This technique utilizes a one-month LIBOR forward yield curve matched to the identical maturity term of the instrument being measured. Observable inputs utilized in the income approach valuation technique incorporate identical contractual notional amounts, fixed coupon rates, periodic terms for interest payments and contract maturity. The fair value of the interest rate swaps also considers the credit risk of the Company for instruments in a liability position or the counterparty for instruments in an asset position. The credit risk is calculated using the spread between the one-month LIBOR yield curve and the relevant interest rate according to rating agencies. The inputs to the fair value measurements reflect Level 2 inputs. Assets and liabilities associated with the Company’s interest rate swaps as reflected in the Condensed Consolidated Balance Sheets were as follows (in millions): March 31, 2021 December 31, 2020 Assets: Other current assets $ — $ 1.9 Other long-term assets 18.1 0.3 Total assets $ 18.1 $ 2.3 Liabilities: Accrued expenses and other current liabilities $ 3.2 $ 4.2 Other long-term liabilities 17.9 40.6 Total liabilities $ 21.1 $ 44.8 The following tables present the impact of the Company’s interest rate swaps (in millions): Amount of Unrealized Income (Loss), Net of Tax, Recognized in Other Comprehensive Income (Loss) Three Months Ended March 31, Derivatives in Cash Flow Hedging Relationship 2021 2020 Interest rate swaps $ 27.8 $ (31.6) Amount of Income (Loss) Reclassified from Other Comprehensive Income (Loss) into Statements of Operations Income Statement Classification Three Months Ended March 31, 2021 2020 Floorplan interest expense $ (2.2) $ (0.6) Other interest expense, net $ (0.9) $ (0.1) The net amount of loss expected to be reclassified out of Accumulated other comprehensive income (loss) into earnings as an offset to Floorplan interest expense or Other interest expense, net in the next twelve months is $3.2 million.

The Company may be involved in legal proceedings or suffer losses that could have a material adverse effect on the Company’s business. In the normal course of business, the Company is required to respond to customer, employee and other third-party complaints. In addition, the manufacturers of the vehicles that the Company sells and services have audit rights allowing them to review the validity of amounts claimed for incentive, rebate or warranty-related items and charge the Company back for amounts determined to be invalid payments under the manufacturers’ programs, subject to the Company’s right to appeal any such decision. Legal Proceedings As of March 31, 2021, the Company was not party to any legal proceedings that, individually or in the aggregate, are reasonably expected to have a material adverse effect on the Company’s results of operations, financial condition or cash flows, including class action lawsuits. However, the results of current or future matters cannot be predicted with certainty and an unfavorable resolution of one or more of such matters could have a material adverse effect on the Company’s results of operations, financial condition or cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Financial Statements and notes thereto, have been prepared in accordance with U.S. GAAP for interim financial information and in accordance with the rules and regulations of the SEC. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. Results for interim periods are not necessarily indicative of the results that can be expected for a full year and therefore should be read in conjunction with the Company’s audited Financial Statements and notes thereto included within the Company’s most recent Annual Report on Form 10-K. The accompanying Condensed Consolidated Financial Statements reflect the consolidated accounts of the parent company, Group 1 Automotive, Inc., and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been eliminated in consolidation. Certain prior-period amounts have been reclassified to conform to current-period presentation. Specifically, the long-term liabilities associated with the Company’s interest rate swaps have been combined into the caption Other long-term liabilities in the Condensed Consolidated Balance Sheets. The reclassification within the Condensed Consolidated Balance Sheets had no effect on any subtotal in the statements. Additionally, repayments and borrowings on the Company’s real estate related and other debt have been combined within the captions Repayments on other debt and Borrowings on other debt , respectively, in the Condensed Consolidated Statements of Cash Flows. The reclassification within the Condensed Consolidated Statements of Cash Flows had no effect on any subtotal in the statements.
Use of Estimates	Use of EstimatesThe preparation of the Company’s financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date and the amounts of revenues and expenses recognized during the reporting period. Management analyzes the Company’s estimates based on historical experience and other assumptions that are believed to be reasonable under the circumstances, however, actual results could differ materially from such estimates. The significant estimates made by management in the accompanying Condensed Consolidated Financial Statements include, but are not limited to, inventory valuation adjustments, reserves for future chargebacks on finance, insurance and vehicle service contract fees, self-insured property and casualty insurance exposure, the fair value of assets acquired and liabilities assumed in business combinations, the valuation of goodwill and intangible franchise rights and reserves for potential litigation.

Fair Value Measurement	Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the most advantageous market in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy that 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 for identical assets or liabilities in active markets. • Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or model-derived valuations or other inputs that are observable or that can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Derivative Financial Instruments	The Company’s interest rate swaps are measured at fair value utilizing the option-pricing Black-Scholes present value technique. This technique utilizes a one-month LIBOR forward yield curve matched to the identical maturity term of the instrument being measured. Observable inputs utilized in the income approach valuation technique incorporate identical contractual notional amounts, fixed coupon rates, periodic terms for interest payments and contract maturity. The fair value of the interest rate swaps also considers the credit risk of the Company for instruments in a liability position or the counterparty for instruments in an asset position. The credit risk is calculated using the spread between the one-month LIBOR yield curve and the relevant interest rate according to rating agencies. The inputs to the fair value measurements reflect Level 2 inputs.
