Well...after the R32s absolutly decimated the competition they were either banned or (in japan at least) got their own championship. You could almost say the GTR killed group A racing (cest la vie). 350Z isnt the same. No AWD and non turbo.
I don't like the 350Z concept OR the real car. Theyre both horrible in my eyes. HOWEVER after looking at the "New GTR" again Its not as bad as I though. Flatten the roof, less agressive front grille, bring back an uprated RB26 (V6s are the most evil engine in the world and should be banned) and Id make a marked effort to accually buy one.
