Have owned BWM, Volkswagen, and Volvo vehicles. This MB is by far the best in terms of build qulity, ride, and engineering. This is my first diesel, so I'm hoping for a huge improvement over my current SUV (16 mpg). The design is timeless and the car feels like it will go hundreds of thousands of miles.
CDI engine (power!), keyless go, bi- xenons (they light up the night!), ambient lighting, summer opening feature (windows/sunroof), electronic trunk closer, sensuous body lines, MPG, steering wheel entry/exit feature, MFD that lights up when using cruise control, jealous stares from strangers :)
Navigation is too complex/too many buttons. Remove key chime w/keyless go. Ability to scan preset radio stations from steering wheel. Can't add MB SAT radio unless you order it from the factory :(
