I bought an '08 camo brand new. I loved the machine; however, the gas cap location is little to be desired. The only issue I ever had with it was the amount of heat the engine put out made the gas boil...I know it sounds stupid, but I took the cap off after a ride and the gas just spewed out all over. IMO, the power and suspension are much better than my '09 Suzuki King Quad 750AXI.
When I go back to a ATV , it will be a Grizzly . Dirt Wheels has ranked them #1 for about 5 years . They may not be the best in any one catagory , but they do everything well . Great allaround machine .
My buddy had the 660 and has the 700 now. Both are great machines. Great do all quad and very comfortable. I believe there was a recall about the gas heating up. My buddy took his to the dealership and they installed a heat sheild I think which solved the issue. You can't wrong with a Grizzly.
