I'm looking at a 95 E320 wagon. $7500 with 88K miles. The owner says the head gasket has never leaked and thus is original. I haven't asked about the wiring harness. Question, where do I look for this harness to investigate myself? Is this a good deal or should I run away. The car has clearly been taken care of as many of these cars are pampered by their owners. Any advice and orientation would be appreciated.
