Mercedes-Benz E420 Reviews

Great car but has a poor Electrical Wiring System
The ASR light came out and the ABS light same time came on and all gauges stopped working. When engine was shut off, it could not be started and all the lights came on.
This is a wonderful automobile. You have to drive one to know.
