I'm hunting for my first MB (joining ranks with my Dad, a MB owner), and am looking at a 1983 300SD on Friday.

Is there a list of known/common issues that I should look for? I'm going to try and get it to a MB dealer for a check-up before tendering cash, but I want to make sure that it's at least somewhat viable.

Also, any comments on price? I has some noticable body rust (welcome to the midwest), with a little over 200k miles.
