Nice video. At 56 seconds you can see in the background the progression of the Stingray and Corvette emblems, and also a stealth bomber.
In other places you can see myriad illustrations of interior and exterior design. It's clear they thought about everything and didn't merely copy Camaro or anything else.
For those compelled to sing the tired song about designers copying the viper, GT-R, Camaro or whatever...see my earlier post about originality and the narrow window for the marriage of form and function.
I think Longtimer mentioned that TJ said there was no exterior design clinic. Yet Car and Driver magazine specifically call out the issue and state that a corvette enthusiast suggested that the rear-end had not really changed in 25 yrs.
