Thank You for the warm welcome. I'm from Germany, and I have just discovered AutoPuzzles. I'm quite fascinated by the high level of the puzzles and by the fact, that I recognised some well-known names like Pal Negyesi (whose KTUD archive I've been knowing for years) or Hugo90 (whose car-related pictures in flickr are always interesting).
Back to the Mystery Car. If it is not french, it must be Italian, or am I wrong again?
