Seems to me this bike went for about 700 bucks more than it's worth, based on past auctions of the same sort... this does have an interesting set of graphics...the head-badge decal looks like some sort of transition graphic between the early 70s design and the more common one that is still in use.
It looks like two guys got into a bidding war for it..otherwise, it's hard for me to figure out why this went for so much more than the usual.
