Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued OperationsOn May 30, 2018, we acquired Stahlgruber GmbH ("Stahlgruber"), a leading European wholesale distributor of aftermarket spare parts for passenger cars, tools, capital equipment and accessories with operations in Germany, Austria, Italy, Slovenia, and Croatia, with further sales to Switzerland. Prior to closing, on May 3, 2018, the European Commission cleared the acquisition of Stahlgruber for the entire European Union, except with respect to the wholesale automotive parts business in the Czech Republic. The acquisition of Stahlgruber’s Czech Republic wholesale business was referred to the Czech Republic competition authority for review. On May 10, 2019, the Czech Republic competition authority approved our acquisition of Stahlgruber’s Czech Republic wholesale business subject to the requirement that we divest certain of the acquired locations. We acquired Stahlgruber’s Czech Republic wholesale business on May 29, 2019 and decided to divest all of the acquired locations. We immediately classified the business as discontinued operations because the business was never integrated into our Europe segment.We completed the sale of Stahlgruber's Czech Republic business on February 28, 2020, resulting in an immaterial loss on sale (presented in Net loss from discontinued operations in the Unaudited Condensed Consolidated Statements of Income). As part of the transaction, we purchased the 48.2% noncontrolling interest from the minority shareholder for a purchase price of €8 million, which included the issuance of €4 million of notes payable, and then immediately thereafter sold 100% of the business for a purchase price of €14 million, which included €7 million of notes receivable. This transaction resulted in a disposition of noncontrolling interest of $11 million. From January 1, 2020 through the date of sale, we recorded an immaterial amount of net income (excluding the loss on sale) from discontinued operations related to the business, of which an immaterial amount was attributable to the noncontrolling interest.
