Someone will buy it. Maybe even a collector since it is such a low vin. Thought there was an agreement they can't sell the car for over msrp so will be interesting to see if they take it down and get threatened with legal action.
There is nothing stopping them from selling it to their buddy for MSRP, and then their buddy can sell it for anything they want to. (I don't think Tesla can put a "deed restriction" on the car that would prevent future owners from selling at over MSRP.)
