I am thinking of buying a 350z this spring..prob track model...is this a good car for speed and handling.. what does the track model have to give it 13 more horse than the other models...what performance upgrades are out there, and best bang for your buck...i have also been looking at mitsu evo, subaru wrx sti, and honda s2000, why would the 350 be better....i have owned 89 5.0gt mustang, a 2000 gt mustang and a 94 mitsu 3000gt vr4, how would it compare to those....
