Run away from Mercedes, it is a poorly designed car that uses expensive parts of poor quality. This car reminds me of the mid 70's junk that Detroit put out. Dumped the car. Avoid Mercedes and buy an Audi, Ford or anything else
Purchased new, and as an everyday driver, we've logged 18k. The car's excellence is diminished only by a few ergonomic issues. The heat controls for the seats are mounted on the door, making it impossible to adjust without taking your eyes off the road, and don't get me talking about programming the GPS! It has an outdated feel - My mobile phone is much better! The drivetrain shifts smoothly, and the engine delivers the perfect combination of torque and horsepower. If the interior design falls behind the outstanding engineering of the rest of the car.
Build quality, handling , ride quality - the adjustable suspension delivers a smooth ride when cruising, but firms nicely up with spirited driving. The engine has been reliable and gets good gas mileage for a high output V8
Just do away with lame GPS, and incorporate an interface for my iPhone's better performing GPS
