I have not been happy with repairs on either of the two Polaris models we have had. Starters, belts, pulleys, fuel pumps, and regulators have failed, sometimes more than once.

I got a 2013 Yamaha Kodiak 450, and so far so good. I live on a farm and use them for weed spraying, hauling irrigation fittings and pipe, herding a few cows, and that sort of stuff.
