Base + Sport + Mats/Kicks/Aero = ~$32,200
Nismo + Mats/Kicks = ~$37,600
I AM A NISMO OWNER
$5,400 can easily buy some Coilovers, the Nismo bar package, exhaust, and a Cobb. That will be
better than the Nismo.
I personally like the cosmetics and wheels, and the fact that it's "limited edition" (not really.) If I didn't feel that way I would've financed the same $40k-ish and gotten the parts I listed above plus an In-Dash, CAI, and headers.
EDIT: forgot about the oil cooler that I now have too.
