“Recently I found out that the wiring harness on my 1991 600 se is deteriorating, on some places you can already see the bare wires. This car is in desperate need of other repairs, and before we can do anything else we must replace every single harness in the engine bay. We are not a very rich family and can not afford that. I have to drive the car almost every day and am very worried about the safety of it. Why doesn't mercedes do something about this? That is beyond me.”
