I agree with Mike, a 650sx will be a much better choice. That one is in kind of rough shape. The bottom doesn't seem to be trashed, just the turf and the area where the chin pad goes. try and talk him down some more because turf or a pad kit will be a couple hundred bucks at least. If you do buy that one make sure to get the oil block off kit and get rid of that oil inject system. Its bound to fail and when it does your whole engine will be shot. If I were going to buy that ski I would buy a hydroturf pad kit asap, replace the turf on the bottom of the tray, give it a good buff and wax, and then go enjoy your brand new looking ski.
