The most annoying thing about the Nismo is that it isn't FI from the factory, and for the price difference it should be.
I mean, Ford gives you a lot of performance upgrades when you shell out for a Boss 302 or GT500. Why can't Nissan do the same?
It's easily the best looking 370 out of the box though.
And if you do decide to mod a Z to end up with a better car for less money, start with a sport package; the base won't come with decent wheels, rev-match, or the LSD. All of those are things you want.
