CarMax sells, finances, and services used and new cars through a chain of 220 used retail stores at the end of fiscal 2021 plus one new vehicle store. It was formed in 1993 as a unit of Circuit City and spun off into an independent companyin late 2002. Used-vehicle sales account for about 83% of revenue, wholesale about 14%, and the remaining portion is composed of extended service plans and repair. In fiscal 2021, the company retailed and wholesaled 751,862 and 426,268 used vehicles, respectively. CarMax is the largest used vehicle retailer in the U.S., but still estimates that it has only about 3.5% U.S. market share of vehicles 0 to 10 years old but seeks over 5% by the end of calendar 2025. CarMax is based in Richmond, Virginia.
