couple things to look for:check for vin number,check swing arm pivot bearings(lift back of quad up to where the back tires r still touching ground and move side to side see if theres any play) check all geusets on the frame for cracking(near air box esp). and then pretty much just over look the hole bike and make sure YOU feel its worth it. banshees are a blast to own and ride and i traded mine for a 93 bagged s10 and have never looked back and/or regretted it. good luck!!
