It is not so much the body styling that counts, as lomg as the chassis is original. The Bentley Mk VI is a very crude chassis which needs complicated alterations to be attractive. Any alteration however may be in conflict with the rules of the particular authorities and therefore it might be possible that you won't get your car on the road (legally).

In the UK it is not so diffucult to get a home made car on the road, in Holland, however it is.
The Bugatti chassis was unaffordable so we are looking still around.
