My E320 CDI (Turbo diesel) is a joy to drive. Mileage is amazing. A wonderful, solid feeling road car. Interior is miles ahead of BMW 535 and Audi A6. I drive 300 miles a week and I only get fuel once every 2 weeks! Navigation system is excellent as is the suspension. This car has been tweaked to near perfection. As promised by the dealer, cold weather starting is fantastic - 3 seconds of glow plug operation in 10 degrees and it starts faster that gasoline engines - WOW! My dealer, Leikin in Willoughby has been great. Mercedes is working very hard to make sure you love the vehicle and the dealer. Lots of surveys to insure satisfaction.
Solid, safe road manners yet stunning acceleration when you "put your foot in it". Interior is extremely well designed - very classy. Mercedes has worked very hard to make the car driver friendly and intuitive.
