My friend has a G37s (essentially the same thing) with KW V3's, Volks, Exhaust, air intake, oil cooler...ect. But the car doesnt seem to be as well composed as my E46 m3.
Interior is far better than my M3 though, thats for sure.
I had the old 350z and the interior was utter garbage. A coworker bought the new 370z and it was a little better but nowhere near my E92 M3 interior or my E86 M. Not even close.
However the 370z looks good with a kit and nice wheels. I would go with the newer car in the Nissan. But for looks the E46 M3.
