Looking for a car you used to own, or interested in the history of your current car?

Owned (and sold) by me in the mid 70's. This Conifer Green example has been sorely missed ever since.
Registered in central London, the second owner in the buff log book was listed as C.I.A - Helensburgh, not far from the US Neuclear sub base at Faslane. So much for covert operations!
DVLA tell me the number is no longer 'live', but do point out that it may never have got onto their records in the first place. So, if anyone has seen or heard of this long lost friend, please let me know.
