1980 Mercedes 300 SD Turbo Diesel

1980 Mercedes 300 SD Turbo Diesel. Starts easily, uns and shifts well. I will post as many pictures as I can to show its great condition.
Limited information on car due to the fact that I bought it from a charity auction that benefitted Oregon Public Broadcasting (it was a donation). No service records are available.
Power antenna for radio doesn't go up (radio works). Front passenger power door lock and window aren't working (door still locks and unlocks manually).
I will do my best to answer any questions. Buyer is responsible for pick up and transportation of vehicle.
