Hi, I'm looking into buying a new or slightly used 4 seat UTV that I could take to So Cal deserts (Ocotillo Wells and Imperial SD) or up to Mammoth for mountain trails. It doesn't have to be super powerful but enough to have some fun in. This will be my first UTV. The two most important criteria for me are 1) reliability 2) fun! So far, my top choices seem to be Teryx4 and RZR XP4 900...with the T4 seemingly winning the reliability factor and the RZR winning the fun factor. Any others I should be considering?
