Good questions and good observations there.... Here is my two cents. I am a 07 Ranger XP700 owner on the mature side (over 50).
My nephew has a Ranger and his good buddy has a rhino. Both have their pluses and minuses. I rode rode both before deciding on the Ranger and it was purely decided for a comfort reason. I like the bench seat of the Ranger, the wide platform, and the somewhat smoother ride. I am not the dune jumping, ridge hopping sort. I like to explore the desert and mountain trails. I also wanted a reliable machine. This is where I made my mistake. Apparently many newer Ranger owners, more so the 2007 owners, are experiencing problems with a defective front lower motor mount that comes apart causing the drive belt to shred. Polaris apparently refuses to acknowledge the problem, leaving its customers to fend for themselves. So I would seriously take into consideration factory customer service when you make your decision. Otherwise, the Ranger is a great machine that serves my purpose well. It is just not a reliable machine. And that is not a very good thing!
