The rear-wheel drive C Platform designation had been introduced as early as 1936 and was used until 1984. From at least 1941, when the B-body followed suit in adopting the C-body's pioneering lower and wider runningboardless bodystyle, it may be viewed as a stretched version of the GM B platform. After 1984, the platform was renamed the GM D platform and continued in production to 1996.
This platform was the basis for the following vehicles:

From 1985 onwards, the C-body designation was used for front-wheel drive luxury cars. The platform 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 briefly made its return on this platform, stretched by 23.6" to a wheelbase of 134.4".
