Which exhaust did you opt for? I only lasted 2 months with my standard set-up before installing a cat-back Cobra beauty. Had the car for two years now and never tire of driving it.
I think the 370z is one of the nicest looking Asian coupes made. I wanted to buy one of these so badly, but absolutely had to have a back seat, so I went for a Hyundai Genesis Coupe 3.8, very similar but just a little bigger and a touch more power.
