I seriously don't understand why people complain about the road noise. I commute 40 miles a day and yes, on certain bumpy parts of the freeway I can hear more road noise than usual but on regular roads it's almost as quiet as my 335i. It actually rides better too. My 335i has the sport package with 18" Potenza RE050 Run Flats, boy do those ride rough.
My ONLY complaint about the 370Z is that there is no back up camera, come on now....40K car with navigation and no backup camera with limited rear view visibility like this? You gotta be kidding me? I also wished the 3rd gauge pod on the dash was something other than a clock, maybe a G meter or something cool.
Other than that, there is absolutely nothing else I can complain about
