I'd rather the better car. Or a Supra (or the new one, if I could ever afford it >.<).
You want to do different things, obviously.
For me, the gt-t is great because it can make ridiculous power (there are 400 + kw gt-t's on the street) with the neo 25, it's a single turbo also. So there's no need for the rb26 (although I want one
)
The gt-t can handle just as well as the gt-r, because let's face it, no enthusiast keeps the stock coil overs and sway bars, and everyone beefs up the Engine brace.
The gt-t looks as good with a body kit, all it really needs is suspension and brake upgrades to handle like a gt-r, which a lot of gt-r owners do anyway, but if I want to take my car to Queensland raceway and slide it I can, or I can get around a track just as fast (as long as you are a good driver).
Plus they're 40 k cheaper. 40 k worth of mods would get you a gt-t that would maul a gtr
Supras are cool, don't like the dated interior though. The 2jz is a beast.
Do you mean new supra or new gtr, coz I wasn't aware that there was a new supra.
