I vaguely remember MB lost one class action law suite in the late 90's to these 140 car owners. I think each owner got a coupe thousands dollars of credit toward purchasing another car or something like that.
I think the mass air sensor, head gasket, and time cover gasket on the 103 and 104 motors are good candidates for actions. Could anyone reasonable imagine that the above three are "wear" items at 50 kmi? Obviously MB do.
