If you look at how the classes are broke down beyond body design/redesign. I think that the 79-93 class should be broken down a bit further. There is a vert class already. I suggest classes iclude such classes as GT, LX, Coupe, Hatchback, 4 cyl., Cobra.
These are only suggested classes. But if you look at the listings for the 94+ classes, there are alot more breakdowns than in this class.
