I am in the market for a 4x4 quad. I own a auto repair shop and I am getting too old to be pushing dead cars in and out of the shop. I decided to look for an older 2000 to 2004ish 4 wheeler. I want something big and heavy with a lot of grunt(no smaller than a 400). It will also be used un the fall for hunting and may even head to colorado after elk. I rode a lot of trails on 2 wheels when I was younger so an outmatic feels kinda strange to me but I could get used to it. There are a couple I have models I have been eyeballing one is the yamaha 600 griz and the other is a polaris 500 sportman. Is there anything I should be on the look out for? Anyother model you would recommand(i am not a kaw fan)? I know the 2 i mentioned are belt drive, is that an issue for working them hard?
