I know one of the previous owners of the car - not sure if he’s on here - but we were recently talking about it on one of our regular telephone chats. He said that he loved driving it; “ a real classic driving experience”, he said.
Keith at BHM knows the full history: If my memory serves me correctly, I think that the owner who had the supercharger fitted spent quite a lot on it, as he also had a lot of other work done.
You could talk to Sarah first - they have asked some sellers to take the cars back for safe storage during the lock-down, so I’m not sure that the vehicle is at BHM at the moment.......
