This four door version by Henry Chapron is a stunning example of French design at its best in a formal body style. We know too little about the cars of Henri Chapron.
Just found out about this car recently. I always thought the Citroen SM was one of the best looking cars out there, but I was annoyed that only a hatchback version seemed to exist, so you can imagine my surprise to find a sedan version. I think it looks even better than the original, just a shame they're so rare. Guess it confirms that I'll never own my dream car :(
