I had a 1995 Mercedes E320 that had every bell and whistle that Mercedes offered. I bought it used when it was a year old, and took very good care of it, and when it had about 50K on the odometer in 2000, I put it in the garage for the winter but never got around to taking it out of storage for the next 15 years. When I finally took it out, the interior was full of mouse droppings, so I had my neighbor detail the car. Zero smell of mice when he was done with it, and a new battery and it was running like a new car. The only thing that didn't work was the transmission shifter wouldn't release. The mice had chewed the wire, but I couldn't find the break. I had kept comprehensive insurance on the car for all those years since it was part of the homeowner's policy. The insurance company called it a total loss and paid me for the car. That was the era when Mercedes had problems with the wiring, and my car had every wire hand wrapped by the dealership when I purchased it. After the car was taken away I learned that the wire was above the transmission and that the only way to see or get to the wire was to remove the transmission. If I had known that, I would have bought the car back for the salvage value.
