Need some feedback. I am thinking of buying a used 2011 RZR4. It has about 800 miles, with some accessories and remainder of 5 yr warranty. Does anyone have anything to say about the 11 RZR4? It will be a trail machine for me, my wife, and two kids. We ride mostly woods. I currently own a RZR S. I just wanted to get some feedback on the RZR4.
