Depenon the year, Have a look at it and look for tears in the seat, creases in the tunnel. Stand on it and see if they ski's are level with each other, tip it on its side and look for creases around were the a-arms hook up to the bulkhead and around the front cooler. (if you find any then the nun is busted and its 14 hour job or so to replace it.) they are a fun sled if you need a sled that can handle serious abuse. They are alot of work however with constant jetting adjustments. They can be pretty hard on gas and if you are not used to mixing gas it can be daunting for some people.
