I absolutely love the way that the 370Z Nismo looks, but the fake interior noise and the very quiet standard exhaust do come in for a fair bit of criticism(the later model). The exhaust is an easy fix though, and I presume that you can disconnect the fake interior noise as well.
From what I read the 370Z Nismo is much more sharper to drive than the standard 370Z. The looks of the 370Z Nismo are heavenly for me.
