Once you start adding it all up, taking into consideration all the packaging/boxes included and the rarity of some of those items, the BIN price may not be that far off a fair amount. One might even be able to squeeze a little more selling pieces separately, which this guy might have to wind up doing.
Chances are, the body will require a completely strip down and overhaul before it would work 100% properly, noting the carefully worded statements around the mechanical condition. Of course, this is also more a collector than user-driven setup in terms of where the prices might go. He possibly could have chosen a lower starting bid with no "Buy it Now" option, a reserve and done better.
Set ups like this don't come around very often.
