I purchased a 81 300 SD in March, and it consumes way more oil than the person who sold it to me claimed. ALso He thought it was from leakage, it's really from burning it. THis is turning into a nightmare for me. THe car seems to run great, has good power and looks nice. But the oil thing a big deal. Basically I'm trying a last ditch attempt to clean the engine, otherwise it's a new engine or junk the car. So buyer beware! By the way, I did have it checked out by a reliable mercedes shop and they said all was pretty good also. I paid $2000 for the car, high on the scale, but this car looked and ran well, I saw many others from between $800 junkers to $2500 or so. Good luck!

Also I've had to replace my turbocharger ($1000 for a used one installed), and do a bunch of other stuff. i expected to put some money in, but not like this...
