Price sounds good for what you are getting. Find out if the previous owner was a poster on this site if you can--and then read all his posts to see any issues he had. And look for any scratches and damage from dropping the bike, these fall over easily and many are busted up; they can actually be TOTALLED by letting them fall over on the side. Reduce value by price of plastic damaged. And look closely at the nuts and bolts, if you see ANY rust from parking outdoors, or deformation from hamfisting, that's a deduction.
