I love the car. However, in spite of the fact that I drive it less than 12,000 miles a year, and always on well-kept expressways, I have had to replace 4 of my Continental tires in the past 15 months for bulges in the sidewalls "caused by pot holes" according to my MB service rep!
Drives like a dream - in spite of it's smaller engine. A long trip is a pleasure.
Continental tires are really poor quality, and the manufacturer doesn't stand behind them - very subject to bulges in side walls.
