How is it irrelevant? I have been going since then and never stopped. Unlike most GM guys I have owned or worked on everything else too and I am plenty capable of knowing what they run for times and the power they can make.
Yes, they do need more power due to weight and aerodynamics. And I like the Z06 regardless of who makes it. But all the nonsense that “a bolt on GT500 can’t keep up with a stock Z06” is retarded.
The original comparison was a NEW car, I could go ahead and toss my LX in to the comparison if we are talking used cars but that is retarded. A new GT500 is $47-55 depending on options, sticker price. For the extra price difference you could slaughter a Z06 and have less $$ in it.
