las769 - Thanks for the heads up on the wiring harness. I'll definitely get one with the updated harness (or adjust the purchase price for a replacement)

deanyel - The ICM on the 90-92 is what's scaring me. I believe it's something like $3,000 to replace. But my question to the mechanics is whether or not this is a big problem or only limited to a small number of cars. Also, if this unit is replaced, is the replacement better than the original? (Will I still have to worry about it if it's been replaced?

antonino - I believe it was in 96 that Mercedes started cutting corners to compete with the Japanese models. The 93-95 models are almost the same as the 90-92 except it has HFM. Don't get me wrong, if I find a well kept 90-92 W124 coupe I'd buy it. Right now I'm just trying to do my research to avoid the headaches.


All models have problems with the head gasket, evaporator, radiator neck
90-92 have problems with the ICM ($3,000 fix)
93-95 have problems with the wiring harness ($600 fix DIY)

88-89 have the M103...so far this seems like a "SOLID" engine, but I'm not sure if I'd be able to find a well kept one. Downside with these engines are is lack of power and poorer gas mileage.
