If you want to take on the burden of buying old Bentley parts when it brakes I bet the owner won't give a damn lol. We had a 98 Brookland on the lot once listed for $20000 (or somewhere around there) but the new radiator it needed was close to 5k.
To be honest it completely slipped my mind that it would still be there property even off their property. Only legal way would be to buy the parts off the rebuild shop.
