STORY

Grand LeMans was the top trim of the Pontiac LeMans intermediate line. The Luxury LeMans of 1973 was renamed Grand LeMans in 1975, and its Colonnade body ran through 1977. The 1973 Luxury LeMans used a 350 V8 rated at 150 hp as standard equipment, with a 400 and a 455 optional. The 1978 redesign moved to the downsized A-body on a 108-inch wheelbase. The mid-size LeMans line ended after 1981, and the Pontiac 6000 became its successor.
