the na by design is meant to be the slower 300zx. The car is for those who want a nice looking, good handling, 'quick' car. Now if you want a fast 300zx (big diff between quick and fast), you get the TT. If you get suckered into an na, either A) sell it and get a tt, or B) throw a vg30dett in like may other and I have done =)
