The Pontiac Trans Am was an automobile produced by Pontiac, a division of General Motors (GM), to appeal to the growing muscle car population. Four distinct generations, based on Pontiac Firebird coupe body styles were produced between 1967 and 2002. These cars were built on the F-body platform, which was also shared by the Chevrolet Camaro.
