FIRST THING IS OBVIOUS CONDITION OVERALL. I WOULD LOOK AT THE SUSPENSION COMPONENTS B/C THEY ARE EXTREMELY EXPENSIVE TO REPLACE. THE FRONT FENDER LIPS THAT ROLL UNDER THE CAR ALWAYS RUST OUT. MAKE SURE IT IS A TURBO MOTOR......
Definitely have a Mercedes mechanic (independent) look at it, paying special attention to the condition of the rear suspension. Unlike the other '81-'85 300 diesels, the wagon has a self-levelling rear end that use a hydropneumatic system - which can be very expensive to fix if not working. Also, check the condition of the hatch; apparently, it is quite common for rust to start there due to failure of the window seal and/or hatch weatherstripping. Aside from that, the same issues pertaining to all '81-'85 diesels apply (i.e compression test, how does trans shift?, vacuum system in good working order?)<br>
Be careful. I just bought an 82 300 sd on the spot. Sounded and ran great got it checked out a few days later and the mechanic said the engine was about shot. Couldn't beleive it. Spend the 50 bucks and check it out!!!
