Wow. I recommend you use the search feature and use words like : wiring harness, OVP, evaporator (sp?), throttle actuator, head gasket, water pump and other qualifiers like 1994, M104, M119, W124 or E320 and E420. The popular opinion here here is that once the bugs are worked out the E320 from '94 to '95 they are awesome cars (I own one) but the E420 seems to be a favorite here.
