Hi guys. First post. I'm looking at '94/'95 E320 wagons with about 100K miles. I'm trying to figure out what it is I should be prepared to fix in case it has not been done. I hope this thread will help others trying to buy used W124 E320's in a "one stop" kind of way.

From the research I've done in the last few days, it seems this is what commonly goes wrong with these cars (I'll edit it as replies and contributions come in):

-Head gasket (might as well do a complete head job while at it) (1)
-Engine wiring harness (1)
-OVP relay
-Evaporator
-Water pump
-Radiator/hoses
-Carbon deposits in manifolds
-Throttle actuator

I'd appreciate if you guys could help by adding items and ranking them in terms of frequency from 1 to 3. For example the head gasket seems to be an issue in ALL cars, so it gets a (1). If only very few people have trouble with the tranny then it gets a (3), etc. A price estimate would be nice too.

Thanks!
