a 65cm seems big even for someone 6'2". Also after reading through the auction, I'm wary of the shipping deal, and how much they'll try to charge you. try to get a quote from them before bidding.
Over all the bike, if it was local, I think I'd probably offer up to about $125 or so. Being that you'd have to ship it, and with that size frame, I don't think it will go for much.
