Your co worker's car sounds like the same example as mine. Has he had the typical wiring harness, head gasket incounters. His mileage is actually the lowest that I have heard of yet. I tell you what, the car I'm looking at seems "new" also. The engine "looked" new. The handling "Felt" new. The interior "is new". WOW!!! It drove like nothing I have ever driven even my 500sel. This would be my wife's car. She has been a "Toyota Camry" girl for more than a decade. When I got my 500sel last month, she realized what great quality and engineering these old benzes really are. I am so excited about having another benz in the stable.
