Buick is one of the pioneering brands of the GM conglomerate, founded in 1908 before General Motors even existed. Buick later served as the second-highest luxury tier in the General Motors catalog, falling only behind Cadillac in price and luxury. It would be an understatement to say that they produced some of the most important cars of the muscle era, including the Buick Electra, Buick Riviera, Buick LeSabre, Buick Skylark, Buick GSX, and Buick Regal.
