Well, I took out the new 2013 RZR 4 today. What a blast was cruising the desert trails and a small dune area nearby. Very happy with the ride, espeacially in the whooped out trails. I was suprised the speed I could comfortably maintain through the bumps. But the best part of all was hearing my 7-year old son and co-pilot continuesly yelling "awesome do that again." This is going to be a great family fun piece.
