But nobody is saying who reportedly paid some around £10m. for the car with licence plate number 08.
The car is called the 'Sweptail', with the name coming from the fact that it was inspired by the classic Rolls-Royces of old, with a swooping rear end.
A more modern concession is the giant glass roof, which resembles a boat when seen from above.
It is the only car of its kind and was reportedly requested by a buyer who is a connoisseur and collector of 'luxury cars, superyachts and aircraft'.
