You said Muscle Car. To me a Muscle Car is an intermediate body style, big engine, fairly light. So that takes out the plump wing cars and the overweight Chargers, no pony cars either. This one is in the dictionary when you look up "muscle car". The 68's were there too, by 70 they were moving past utilitarian and into the fluffy category. I love 71's as well but they had extra bits just for flash too. The 69 R.R. and GTX are the perfect example for me. The off brands aren't as nice, a 69 Chevelle almost makes it as does a 69 GTO but they are just lacking in something and Fords just didn't "make it" either.
Look at those clean lines, nothing there that shouldn't be there. Shiny paint! In! Add some fat tires? In!. Now the real test, what is the one car that looks tough as nails with an off colour fender or the whole car in Primer? Yup 68-69 Road Runner or GTX, beat to hell and with a few dents and primer, they still make you look and wonder if it might clean your clock in a race. No other car has the "it" like them.
