can’t disagree with anything you said and have thought exactly this for years..what if it stayed original…….biggest diff with the vette would have probably been weight….as fast as some mustangs were they had a back seat (one of the reasons I find the AMX so appealing, it could literally be placed in the same category) so not a fair comparison….
by a step further, I meant exactly that, a more exotic, better performing much more unobtainable car…..Chevy kinda confirmed the whole thing with the short lived Cheetah….interesting topic…
