i have owned 6 mercedes so far, have 2 at the moment and dearly love everything about them except the dash controls. these are brilliantly designed and engineered cars up to the point when the switches go in and thats when the chimps take over. if you drive the car for 10 years you will still have to dig out the owners manual to get the heater to run on the 1st cold day. to make matters worse my present 2 cars, both the same year but different models have completely different and totally confusing dashes.
