CarMax Inc

CarMax operates a chain of 250+ used-car retail stores across the U.S., making it the largest used-vehicle retailer in the country. The core business is buying and reselling used cars directly to consumers at no-haggle prices, plus selling vehicles wholesale through dealer auctions. Revenue comes primarily from used-car sales (~83%), wholesale vehicle auctions (~17%), and a smaller slice from financing, extended warranties, and repair services. Customers are everyday car buyers; CarMax also runs its own in-house auto lending arm (CarMax Auto Finance), which earns interest income on loans made to those buyers.
