Ok, diablo, what do you call a supercar then? Someones definition was: "Limited amount made, expensive, quick and good looking."
Ok, maybe a normal GTR isn't ALL of those, but the Z-Tune is!
20 were made, they were $160,000 each, they had 550hp and did 206mph and they look brilliant! Although, the looks are debateable (sp?). I really should leave this but you are the ONLY person i have ever met who is adamant that it isn't a supercar.
I'm not asking for a full-stop definition, just what YOU feel is a supercar.
EDIT: Just out of interest, have you been in a GTR? Or a Z-Tune? Or even an R-Tune?
EDITEDIT: Yeah, the thing is though, everyone else i know is either a Eurosnob or a JDM lover, and i only know a few in-betweeners and they've said the Z-Tune is worthy of being a supercar. Except one, but he's only been in an R32 GTS 4-door and from that he now hates GTRs :S.
Btw, i've been in a 520hp Evo VI RS and that was scary :).
