I guess there's a few sellers that are picky about maintainance and avoid the abuse factor, but 99% of what I see in my area are totally beat to death. To bad you're so far away, a buddy talked himself, another friend, me and my wife into all of us buying Polaris 500 HO 4X4s last October. My wife decided she hates ATVing, wants to sell hers for just what she owes on it. It has all of about 40 miles on it, less than 9 hours on the hourmeter and all that's down smooth dirt roads.
In any event, it seems like all the main brands are high quality nowdays, but most everyone agrees, if the smoothest ride is what you like, the Polaris's ride like a Cadillac.
