Whoever bought the OCC cars with the bike included got a whale of a deal. The cost of the bike fabrication was more than what the car sold for!
If the bike were to sell at a motorcycle only auction, there could be no way that it would sell for than less $100K.
As far as keeping the bike and car as a set, it's obvious to me, IMHO, that the bidders were going for the car, not the set.
