Hi there, I have one of these special edition "black" 126's. I thought maybe I had the last UK one left, alas not. Yours is original and mine is actually a replica. I dragged one off a drive in Nuneaton, but when we go it back to Brighton it was far too far gone. There wasn't a single panel that didn't need replacing! I bought a decent one and painted it and transferred all the interior. I replaced my bumpers with NOS from Italy, they have some on ebay.it. Side strips are impossible to get, I have near side rear but still looking for all the others! I made up the graphics from vinyl off ebay, the nearest colour I could find was light brown. I cut the black lettering out with a scalple. However, FYI, there is a graphics kit available now, again it's on ebay.it for the black edition.
Gearbox giving me jip at the mo. Black oily hands again this weekend!
My cousin had a black edition in the early 80s, it wasn't very old but already pretty rusty. She saved really hard to buy it and didn't have it long before it exploded on the oakham to melton road. She was none too impressed!
When i fathom out how to reduce file sizes on a mac book, i will post some pictures.
Enjoy, looks a real find!
