A holding company founded in 1908 by William Durant, General Motors currently sells cars under an array of brands, including Chevrolet, Buick, Cadillac, Holden, Opel, Vauxhall, GMC, Alpheon, Baojun, Jiefang and Uz-Daewoo.
During its bankruptcy in 2009, GM closed down or sold off several brands, including Hummer, Saturn and Saab.
Prior to that the company once made cars and trucks under the Oldsmobile, Geo, Pontiac, Oakland and Bedford marques.
Several concept cars have been badged solely as a GM vehicle, but only one vehicle has been sold as such, the ill-feted EV1 electric coupe.
