Well I did a lot of research before posting the pic, and the conclusion is - Im not sure (which is a shame).
I did have a close look at it and I'd say I'm pretty good at spotting a fake, but the detail seemed good to me. From what I can tell, everything looks spot on.
However (and this is where some may be able to help here), I've done a reg-check and they come back as 'Other italian make', but nothing on age.
It appears fairly common for coupes to be converted, in fact Chris Evans sold his converted coupe, son not sure if that would change any of the details on a reg check?
Anyone any ideas?
