I've got a '59 220S cabriolet, http://www.mbzponton.org/pax058/people/sokoloff/sokoloff.htm. Have had it for about six years. Parts are pretty readily available and reasonable. It's amazing what Mercedes still carries for these cars. See http://www.mbzponton.org/index.htm for more info about the pontons than you can imagine. Consider joining the ponton discussion list at It's a group of about 160 ponton owners who are very, very knowledgeable about the cars.
