Buying 1st RZR this weekend!

Ok.. Long time Ranger owner, deciced i want a RZR for the fam to ride..anybody want to buy my Harley?? Haha, but seriously.. I have found what looks to be a good deal on a 2014 rzr 4 900. Only has 10 hours on it (supposedly). My question from you pros is, what all should i check on this thing? Its a significant investment for me, (did i mention im getting rid of my Harley so wifey will let me have it?) so i dont want to get burned.. Iv seen the way you all drive these things , so what all should i go over?? Thanks! Glad to be a newbie
