I can answer questions on W110/W111/ W114/ W115 /W(R)107/W123/W126 , and Finny Mercedes models 1962-1985. I have rebuilt many of these cars and have problem solved many issues. I have access to much of the technical data and have detailed instructions on fixing the most common issues. Vintage US 1950-1989 and other foreign cars as well If you are going to ask me about car value, please provide ample information on service history, rust issues, and current "needs". Pictures are helpful. Disclaimer on value - I can only give you data on what the market is bringing, and may not be what you want to hear!
