• General Motors first opened on September 16, 1908, as a holding company for Buick. It was based in Flint, Michigan, and controlled by William C. Durant. GM bought Oldsmobile later that year and, over time, acquired Cadillac, Elmore and Oakland (which later become known as Pontiac). Durant lost control of the company in 1910 and founded Chevrolet.
