1978 Mercedes-Benz 300D Diesel

This is a 1978 Mercedes 300D Diesel. The body is in good condition with some minor rust areas as seen in the photos. It has a new battery and new alternator as well as 2 new front tires. It starts and drives. Here is what I know: -I don't believe the A/C works - The power windows all work - The Antenna does not go up - The title is signed and ready to go - The headliner is coming down very back - The seats aren't very supportive and not sure they are even original - It drives nicely - I believe the paint to be original - The Speedometer / Odometer just stopped working Ask any questions and I will try and answer. I am selling for my friend who has been stationed in Germany with the Army. Thanks
