I just picked up a 1982 300d. They are a really neat car. Got it for $300 and drove it home. I'm starting to get her back into shape. I do know the engine needs a rebuild or something on those lines. If you losen the oil fill cap, it will sit and dance on the valve cover. I replaced the injector nossles with the bosio nossles at dieselgiant.com and ran the diesel purge through. I'm hoping to get her all back into shape. The interior is almost perfect. The only seat that looks used is the front driver. The back is perfect. It still has the original med kit. Should probably change the contents. I just bought an entire brake system for the car. New calipers, rotors, and pads. The old system was solid rust. I guess they never changed the fluid. If anyone has some tips for me or any ideas, let me know. I'm all ears.
