I've driven an SRT-4 on a road course. ALL that he can brag about is how fast his car is in a straight line. Because other than straight-line ability, the car is a total P.O.S.. No matter how quick the little guy is, it's a Neon. Crappy interior, roll-happy handling, cheesy little toy-brakes that fade severely after one lap of hard driving, etc.etc... Think about it. A rusty piece of crap Pinto with a crate motor dropped in it would potentially "smoke" your stock GT. But what does that prove, the Pinto would still be junk, just fast junk. Him dogging you is kinda like an '05 Mustang GT owner bragging that he can "smoke" a Mercedes SL500. The Mercedes is so much more of a car, that the fact that a $25K Mustang can make it to the end of a 1/4 mile quicker is fairly irrelevent. I see the same disparity in SUBSTANCE between your '05 GT and you're buddy's econo-box with a turbo.
