Carvana (NYSE: CVNA) and CarMax (NYSE: KMX) are both used car retailers that set firm prices and simplify the buying process. Carvana and CarMax both benefited from the post-pandemic surge in used car sales in 2021, but they struggled in 2022 as inflation and rising interest rates drove away potential buyers. As a subsidiary of Circuit City, CarMax was developed with the same focus on firm pricing, guaranteed quality, and a streamlined customer experience as its parent company's consumer electronics stores.
