 Purchased by General Motors in 1909, Oakland continued to produce modestly priced automobiles until 1931, when it was renamed Pontiac.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.
