he doesn't say what year it is; that can be important since they depreciate so much. also whether it's the original owner.
if you check it out, make sure to look over the joint between the headset and the downtube on the frame. lots of bikes crack there. also look at the right chain stay near the bottom bracket and make sure there is not too much damaged from chain-suck. they all get a little skuffed up there, but the metal shouldnt have any gouges or the like. and dont bring more than $400
