I ve never sold a car with some knowledge of the cars total miles ,only when I purchased a 79 300td did I realize what most mb diesel fans have known for years and that is 200k for an old mb diesel is just its half life.I do have a question about documentation for a future sell ,do you think its necessary to gather all details via Car Fax for the next owner to look over or just rely on the cars over all performance and condition to make the sell.
