Get an R32 GT-R and call it a day. Light, fast, AWD, and will hold its value if you ever have to sell it. Well, so will the supra, but a 350z is a dime a dozen. I've had a supra TT AT and a skyline GTS-T. The skyline was more fun to drive, though not as fast. A GTR is that much better. I will hopefully, be picking up an R32 within a month. Anyways, good luck on your decision.
