After thinking about it, I probably made a rash decision to buy my 85 300Dt. I had a perfectly good buick century, with no problems and only 120k, but I had a friend who needed a car, and offered me $1500 for the buick if I was to buy the mercedes, which was only $900. The car had sat up for over a year, and before that had sat for 3 before being drivin regularly for a few months. Keep in mind I'm a 1st time Mercedes owner, so I'm still learning, and theres a few things that could've been avoided, so don't make too much fun ;D. Here's an abridged list of things I've had to repair/replace to date, or have at least diagnosed:

Bad/faded paint (it was like that when I bought it, but I try not to judge a book by its cover) - $400 if I get a good deal from a personal friend like i've been promised
Worn out shocks - around $250 if you do it yourself and buy your shocks on ebay ;D DONE!
Rear CV Axles - totally preventable had I known about the CV Boot problem, but once again, I'm still an amateur On Order
Cracked/ripped/dry rotted rear seat - A victim of neglect and sun damage, its only the piece of fabric that runs along the rear top of the seat connecting to the 'back dash' or whatever its called. padding is shot there as well. $???
Cracked/worn wood trim - I wouldve done this anyways, as the color of the wood (crap brown) is nasty, but I'm currently sanding, restaining and sealing the trim. about $30 so far
seats worn out - I'll probably do the pool tubing fix, but not near as sloppy as I've seen so far. $20?
Steering box is lose techs said it has to be replaced. abt $150 i think
Oil leak - Broken elbow piece on Oil recirculation valve. $3 DONE!
Cracked Windshield - prolly $150
Valve Adj - hasnt been done in years, but I'm afraid to **** up the throttle linkage. Maybe this weekend. $???
Tires worn by crappy suspension - $250 at the least
New Stereo, all new speakers - $300 incl installation, and the pieces or trim 'Sircuit ****ty' broke cause theyre retarded.
Bad A/c Compressor - prolly around $400 incl parts and labor

This is all I can think of for now....I'll add more later
