I've seen those Bentley couple's for sale cheaper than some of the wild price 80's that pop up , usually with lower mileage too , they are a rich mans tax write off is all and if you have to buy a secondhand one then you can't afford it in the first place . So i imagine one that's suffered a prang is virtually worthless simply because there are no buyers .
If its been on tv and he gets 20 grand for it i wouldn't be surprised if he broke even on outlay and he's had some fun doing it so fair play to the guy .
