Sold the 504 needed a complete engine rebuild. My 505 came from the same family that owned the 504, the owner passed away and his widow called me and asked if I wanted the 505 which I had seen when purchasing the 504.
I also have a 1952 Citroen 11CV Traction Avant, I'm restoring a 1937 Citroen 7C Traction Avant and, I have a 1967 Porsche 912.
