It made a 'sort of' van (commercial vehicle), with a very familiar name!
Sadly I don't know the name of the other vehicle, only that it was a four-wheeled light commercial vehicle.
Have you since forgotten the very familiar name?
No, I never knew the name to begin with. I took the photo of the mystery Puzzle car myself many years ago in the south of France when I didn't know what it was. Very sadly, my friend and our ex-AP colleague CMetisse told me all about the mystery car and background to its maker (name, location, etc.), but regrettably he is now longer with us to share his huge 'voiture sans permis' knowledge.
