There were 6 factory builts and one went as a body/chassis and bits kit.
I participated (50%) in the design and construction of the prototype. By an amazing stroke of luck, I bought the 1st. car back only last year. It had been stored for over twenty years before having two owners when I retrieved it. So, it's covered 15,000 miles from new (1971). I have found the lone kit in the Cotswolds and the third factory built in South London. The second factory built went directly to a Rolls dealer in the Canary Islands. I have a photo, with a number plate (that I am not allowed to trace of course) of what is either the 4th. 5th. or 6th! This first car is the one that was in all the shows, magazines, newspapers & TV appearances at the time. 1st. day on the road was to participate in the Beaulie 100 Year Anniversary of the Motor Car 12th. April 1971. There, now you know almost as much as me on the subject and I can go back into my box and just read the Forum.
