Overall I'm not very happy with my Nitro. My biggest complaint is the road noise. With my work I have driven most every new vehicle on the market, and the Nitro has far and above the most road noise. Not a lot more plastic than other SUVs, but definitly feels and looks cheaper. It gives it almost a hard feel. Mechanicly no complaints, enough power, etc. Fuel economy isn't great, but then thats not why I drive an SUV.
Get rid of the road noise and I can live with the rest!
