A car with this much of a buzz and as awesome of a platform?....of COURSE there will be assloads of parts. Everytime I think about the 350Z, I think to myself, yea...I could drop a third of the price for a 350 on a Z32TT, drop another third of that price on mods, and have a car that would slaughter a Z06 Vette for under half the price....then I see the 350....such a bad ass car.
Have no fear...there will be more aftermarket parts then you'll know what to do with, man.
