GM C platform (1985) (also known as the C-Body) was a front wheel drive (FWD) automobile platform used by General Motors for its full-sized automobiles from 1985 through 1996. It was similar to the H platform, with both sharing the same 110.8 in wheelbase. Most C-body vehicles were replaced with cars on the related G, H, and K platform designations. The Cadillac Series 75 limousine briefly made its return on this platform, stretched by 23.6" to a wheelbase of 134.4".
