Wow. I never knew that. So the hardtop cars had roll down quarter windows, and coupes didn't? I guess my car is a hardtop then, because the quarter windows roll down.Coupe had fixed quarter windows.
Some call them a "Post" car, as is the case with my 70 Superbee.
There is a "Post" when you roll down the window.
As stated in Cranky's input. (Post)
