Man, get the Z32! I loved that car; it has timeless lines to it. Sporty and sexy all the time.
From what I remember, Z31 stands for the 1st gen 3L Z, Z32 is for 2nd gen 3L Z. The Z32 came as NA or TT. If you got the TT, you can easily get 400+hp out of it with a few mods. Exhaust, pulleys, ECU reflash, headers, intake and you're ready to :burnout:
