Sounds like 2-2,500 from your description IMO. Rust is the operative word with a W116. Check it very carefully- I had to "import"one from California- and I live in Florida. Check the window rubbers and, if bad, check the floors below for holes. Check the anti-roll bar mounts along the firewall and the arms that extend into the wheelwells. Early climate control is problematic and expensive. This OM617 model in very good condition seems to be somewhat rare compared with the W126 or W123 chassis.
