The Z is a nice car. If you wanted something smoother & quieter, then go with the G37. The Z is a sports car & isn't going to ride like a Cadillac, or be as quite as a Mercedes Benz while driving. When you buy the Z you are getting what you paid for. Like most of us were not too crazy about the exhaust that came on the car, so we upgrade to a better exhaust system. If you want more hp, then go out & buy the parts to help you reach your goal. It is like watching a movie......some people will like it & others will not. There is no such thing as something being 110% perfect b/c there is always going to be something that should have been better, or done differently. At the end of the day if you do not like something about the car, then change it (exhaust, HU, intake & etc).
