I have an XP4 and love it. I usually have it loaded with people, no shortage of power and suspension is awesome. Another factor to consider is aftermarket stuff. I think Rhinos and RZR's have the most because of how long they have been out and their popularity. A friend of mine told me that we will likely never see a side by side over 1000cc because of how these vehicles are classified from the factory. Something like if they are over 1000cc from the factory then they are more like a jeep, not a side by side. Something like that, made sense the way be explained it. Of course it is likely to be one of those things that "his brothers friends dad told him that be heard it from his wife's cousin who works for Chevy". Either way, love my RZR XP4, highly recommend it. Good luck.
