Well put, why2kmax! I was afraid to type almost the same thing, but now that you opened the door...
The GTO isn't my favorite new performance car, but it's still worlds better than any F-body ever was.
The interiors shouldn't even be compared to one another. The F bodys' were always creeky, rattly and cheap looking. One of the things I like about the GTO is the simple yet well made interior, the use of quality materials, and superior tightness and fit. Not exactly F-body features. I can also guaranty that the GTO is a better driving, more balanced, tighter, more predictable, better braking, better handling, more efficient vehicle than the old F-body ever hoped to be. The F bodies were just like the Mustangs; old technology and quality standards wrapped in a pretty shell.
There, I feel better...
