GMC is a manufacturer of trucks, vans, military vehicles, and Sport utility vehicles marketed in North America and the Middle East by General Motors. In January 2007, GMC was GM's second-largest-selling North American vehicle division after Chevrolet, ahead of Pontiac. General Motors was founded by William C. Durant on September 16, 1908, as a holding company for Buick. In 1909, GM purchased the Rapid Motor Vehicle Company, forming the basis of the General Motors Truck Company, from which the 'GMC Truck' brand name was derived. (Rapid was established on December 22, 1901, by Max Grabowsky. The company developed some of the earliest commercial trucks ever designed, and utilized one-cylinder engines.) The Reliance Motor Car Company (another independent manufacturer) was also purchased that same year by GM. Rapid and Reliance were merged in 1911, and in 1912 the marque 'GMC Truck' first appeared on vehicles exhibited at the New York International Auto Show.
