No matter How much this thing has been Maintained, Get yourself an Etorx set and remove the valve cover. Take a good look at the tops of the Valves and check for numbers, If it starts with 72****** Then tell him to drop the price 1k, If the valve tops have a 75******, thats one less possible failure to happen in the future. Remove the SC intake and try to gently spin the SC wheel by hand. DO NOT FORCE IT. If it spins freely, walk away. Take it from Costijoe, 07's and up.
