1971' Mercedes-Benz Klasa S

The car was purchased in California in 2008. I am the second owner from new. A set of documents (purchase invoice from 1972, several dozen documents from the service in the USA 1972-2006, medal from Mercedes for mileage, etc.) Everything works except the electric watch. It's really in exceptional condition, without any corrosion or leaks. The air conditioning freezes when the air is humid. Music plays, etc. Discussions about price only in private.
