| Additional 402(v) Disclosure [Text Block] | For performance share awards, the grant date fair value of awards used for SCT calculations assumes target performance. To determine the year-end fair values used in the Compensation Actually Paid calculations, we have updated the performance expectations to reflect the latest performance estimates for unvested and outstanding awards at each fiscal year-end date. For options awards, updated market input assumptions (stock price, risk free interest rate, volatility, expected term and future dividend yield expectations) have been used to determine the fair values of outstanding awards as of the identified vesting dates and the relevant fiscal year-end dates using the Black-Scholes-Merton option pricing model. Calculated in the same manner, with the same peer group, as required under Item 201(e) of Reg S-K, measuring the period from the market close on the last trading day before the earliest fiscal year in the table through and including the end of the fiscal year for which cumulative TSR is calculated. | | |

| Non-GAAP Measure Description [Text Block] | Comparable EBITDA is a non-GAAP financial measure. Comparable EBITDA is defined as net earnings, first adjusted to exclude discontinued operations and the following items, all from continuing operations: (i) non-operating pension costs, net and (ii) any other items that are not representative of our business operations (these items are the same items that are excluded from comparable earnings measures for the relevant periods as described immediately above) and then adjusted further for (a) interest expense, (b) income taxes, (c) depreciation, (d) used vehicle sales results and (e) amortization. For a reconciliation of net earnings from continuing operations to comparable EBITDA, as well as the reasons why this measure is useful to shareholders, refer to the "Non-GAAP Financial Measures" on pages 46-53 of our Annual Report on Form 10-K for the year ended December 31, 2022. The 2021 comparable EBITDA amount shown in the table reflects company-wide results. In 2021, for compensation purposes, the Committee determined to exclude the acquisition of Midwest Warehouse & Distribution System (acquired in November 2021 for approximately $284 million) from comparable EBITDA 2021 results. As such, the total amount of comparable EBITDA used for 2021 compensation purposes was $2,429 billion. | | |
