I own a 00'Grizzly.I almost bought the 500 Polaris.Thats why I posted this message to see if I made the right decision for me.The main reason I considerd the 500 was because of its true 4wd.I think they are very impressive in the mud.But if I get some 27''Vampires I believe that will be just fine for me.I do plane on keeping mine 4 a while so to me Reliability is the most inportant thing of all.To me I believe the Reliability of a Yamaha is better than a Polaris.
Thanks for the replys
