Just bought a 1984 MB 300SD on eBay! Drove it home from Denver to West Texas a month ago and am slowly learning about my car. I am the second owner and it has 87,000 miles on it. It is in gorgeous shape...zero rust, paint shines like new, leather is flawless and soft. It spent since '94 in the daughter's garage after the dad died '88 and mom went into assisted living '94. She kept it up like dad would have and drove it occasionally to keep things lubed. Had my guy look at it and found a few smaller issues, but basically acted jealous, so I guess it is a keeper.

 

Here it is before I got window tinting to protect the leather from the West Texas sun (click on it, it opens bigger):
