 Pros: sporty style, very comfortable front seats, fantastic engine power/acceleration, easy set cruise control, above average fuel economy.  Cons: terrible road noise, very bumpy ride almost to the point that you feel no shock cushioning, poor weather stripping allows excessive amount of rain/moisture/dirt around interior door casing (bring towels to the car wash), awkward door lock handle interferes with elbow room, small window makes reaching ATM and drive thru difficult without hitting your head, very expensive run flat tires, uncomfortable rear seats.  This is my first MB and I expected much more of a smooth and quiet ride.
