Buick, formally the Buick Motor Division is an American automobile division of the American manufacturer General Motors (GM). For much of its existence in the North American market, Buick has been marketed as a premium automobile brand, selling entry-level luxury vehicles positioned above its mainstream GM stablemate Chevrolet, and below the flagship Cadillac division. Buick is currently the oldest active North American automotive maker (Autocar, the truck-maker, is the oldest motor vehicle brand) and among the oldest automobile brands in the world. It originated as the Buick Auto-Vim and Power Company in 1899, an independent internal combustion engine and motor-car manufacturer, and was later incorporated as the Buick Motor Company 1903, by Scottish born David Dunbar Buick (1854-1929) in Detroit, Michigan. Later that year, the company was taken over by James H. Whiting (1842–1919), who moved it to his hometown of Flint, Michigan, and brought in William Crapo ''Billy'' Durant (1861-1947) in 1904 to manage his new acquisition. He teamed up with influential Canadian businessman and CEO of General Motors in Canada, Robert Samuel McLaughlin (1871-1972) in 1907 with a 15-year contract for motors. In 1908 GM Holding was founded. David Dunbar Buick sold his stock for a small sum upon departure, and died in modest circumstances 1929. Friend of GM founder, William Crapo ''Billy'' Durant, Louis-Joseph ''Louis'' Chevrolet (1878-1941) worked as a racing driver for Buick and later learned automotive design working there. In 1939 Buick also pioneered the use of turn signals, which did not appear on other car brands until almost a decade later.
