Bought this car with 64K miles, now have 101K miles. Zero problems. The inline six is the only truly balanced engine made, and makes for smooth running at any speed. I prefer to buy American, but this 280 engine is great. Don't waste your time with the 220! And for a nine year old car, EVERYTHING works from power windows, seats, etc. Very impressed. My next car if not American would be the E320CDI (inline six, diesel-sweet!) Just wouldn't want to buy new, ouch.
Hey, my car is 9 years old. My suggested improvements have already been incorporated. But if you are into MB steer clear of new purchases, these cars can't be appreciated until they get some age on them, that is what sets Mercedes apart from any other car, it still runs like new.
