Pontiac originates from the Pontiac Buggy Company founded in Pontiac, Michigan, in 1893. Pontiacs first appeared in General Motors showrooms in 1926, selling over 75,000 units in the first year of production. In 1941 the Pontiac division laid claim to the invention of the "engine option," giving buyers a selection of engines. In 1964 the LeMans GTO, or Gran Turismo Omologato, debuted. The GTO is credited with creating the "muscle car" era in Detroit. The division recently celebrated 75 years in the automobile business.
