Appendix: Body Designations

Article by: Wes Worsham

Below is a listing of the Body Designations that were assigned by GM, and the body styles that they were associated with. It does not get so specific as to break down specific models like Supreme vs. Supreme Brougham, but it is pretty darn detailed, and is very correct.  Also, any time you see "Present" it is referring to "as of 1999," which is where my knowledge and information cuts off.
