Cruising craigslist as usual and came up with a 81 300SD parts car for $150. Went to take a look at it, the body was clean no rust or dents from what i saw. He said it starts but the engine knocks loudly and when running it spews out clouds of black smoke.

Interior seemed ok, missing center console and the top of the instrument panel dash looked like it had been chewed on by rats. and driver door panel missing.
Other then that it was all there.

What do you guys think? i want it for the things i need to replace on my car, if i get this i wont sell my SD ill just use the parts off this one and just sell any other parts on it that you guys or anyone else may need.

But from decribed you think its worth $150?
