General Motors (GM) is moving its dealers' pre-owned-vehicle operations under GM’s CarBravo brand, a national, ​online site it launched in 2023. Starting in June, Chevrolet, Buick and GMC dealers must sign on to CarBevo to sell used GM vehicles with factory-backed warranties. The move is expected to increase the number of used cars that flow through its dealership network by adding non-GM models and older vehicles. The luxury Cadillac line will continue to use GM's traditional certified-pre-owned program. The emergence of Carvana, which sells cars online without the use of a dealership, has increased competition across the industry.
