1971' Mercedes-Benz Klasa S

The car was purchased in full working order in 2008 in California. I am the second owner, I have the original purchase invoice from 1972 and a lot of other documents, e.g. repair and inspection documents in the original.
The car did not have any corrosion, the upholstery is in original condition without any traces of use. The car is in "ready to drive" condition, fully operational.
