GMC originated from the Rapid Motor Vehicle Company, founded in 1901, and became part of General Motors in 1909. GMC trucks debuted in 1912 and gained fame through cross-country expeditions. During WWII, GMC produced 600,000 military trucks, including amphibious models. The brand expanded into ambulances, fire trucks, and buses but ceased bus production in 1987 due to competition. Today, GMC focuses on SUVs, pickups, and trucks. Unicorp Auto Paints offers durable, factory-matched GMC touch up paint and accessories to keep your vehicle looking new.
