If that is representative of the current retail value, or even $50k over for that matter, I can't understand why Barbagello wouldn't have sold it themselves. Especially as it is such a virgin example
When a serious buyer with a long history with the dealer turns up before the car is publicly available for sale, offers them an instant cash deal where they still make a profit, they'll do it.
Alternatively, deal with every idiot out there that is dreaming about buying one, hoping to get finance, wanting to trade some shit heap in, who will pick on the tiniest little detail of the deal and weeks later, the deal falls through because of x,y,z and then the whole thing starts again, all the while the car is accumulating interest on the floor plan.
Same thing is what's happening with the LP640 Roadster that Uber has dibs on. He'll pick that up before any member of the public knows the car even exists.
You make something idiotproof, they'll make a better idiot.
