That car was for sale in the recent past from these folks - http://www.4starclassics.com/

Price wasn't outrageous for a unique car of repute, <£20k, iirc.

I'd say you are correct judging by the number plate on it in this picture:

Holy Thread Revival, Batman......

This one is back out of the woodwork. It seems like its had a little bit of fettling since then. I think it was at a different dealer last year at an asking price of around £47k, now at Duke of London at £41995.
