Bloomberg wrote a good article on this car (without going into the details of the car itself), it interviewed the selling party. He conceded the value is mostly derived from the fact the car was put into a condom the moment it left the showroom floor. The pristine condition of this car is what made it unique. The moment someone starts driving this, expect the value to plummet.
