These cars are rock solid reliable and IMO (hate me for it) better than a w124. They don't really ever break, and the 722.6 diesel trans doesn't have the problems the gas models do.

Only thing I'd check on it shocks amd springs.. and obviously rust. I can't see where your from for some reason. At this age, the springs can crack and shocks are worn too.

How's the glow plugs
