Congrats! You'll be the pioneer!
was just kidding... on the 22th of August this puzzle will be nine months old. It won't grow much older...
It's a self-built car from a Swiss hobbyist. His
first car (second pic) has an NSU Prinz engine from 1962 and was built 1971-75. It's still owned by its builder in a very good condition. Coincidentally (!) I've found it for sale today on a website for enthusiast of the engine's brand.
Unfortunatly I have no additional info of the second and more important car. As far as I know it was built at the beginning of the eighties. (~1983)
more on the 20th of August...
