Paid $14600 for ours with 150k on it. Head gasket just now starting to leak on the garage floor. And, today, the first "problem". Motor quit on the wife. It simply quit. But, cranked right back up, only to quit again shortly later. We ended up having it towed home. I'm thinking a fuel problem, but waiting for a reply from here to figure out what to do next.
Nice little car. Doesn't have the ride of the '85 300SD though. Now, THAT was a car!
