Oakland Motor Car was founded in 1907 in Pontiac, Michigan, by Edward Murphy, a manufacturer of horse-drawn carriages. The following year, another former buggy company executive, William Durant, founded General Motors in Flint, Michigan, as a holding company for the Buick Motor Company. GM soon bought other automakers, including Oldsmobile and Cadillac. In 1909, Oakland became part of GM. The first Pontiac model made its debut as part of the Oakland line in the 1920s. The car, which featured a six-cylinder engine, proved so popular that the Oakland name was eventually dropped and Pontiac became its own GM division by the early 1930s. It was named after the famous Ottawa chief, who had also given his name to the city of Pontiac, Michigan, where the car was produced. Within months of its introduction, Pontiac was outselling Oakland, which was essentially a 1920s Chevrolet with a six-cylinder engine installed. Body styles offered included a sedan with both two and four doors, Landau Coupe, with the Sport Phaeton, Sport Landau Sedan, Sport Cabriolet, and Sport Roadster. As a result of Pontiac's rising sales, versus Oakland's declining sales, Pontiac became the only companion marque to survive its parent, with Oakland ceasing production in 1932.
