This is my first Mercedes. Everything is great except for a few things. The seat back contours are designed/built for very skinny people. Even a Mitsubishi I had with wrap around seat backs, were adjustable. The dial temp controls aren't very accurately adjustable (the 2002 Avalon I have are digitally adjustable with rocker up/down 1 degree increments). Ride & handling are superb for a convertible. Body is rigid with almost no twist on tight turns. Engines today should not require premium gas. The menu system is not very user friendly. And I just found out that the Nav. system is only updated every 5 years. Good thing I have portable Garmin units (which are easier to program).
The quietness of the Cabriolet. Top up down operations function including integration with windows. Transmission smooth & quiet.
Touch screen Nav, annual Map updates at a much cheaper price tag (Garmin's free for life) Move cruise cntrl set lever away from turn signal's- a real safety hazard in the dark. Door design makes for a cumbersome entry into rear seats, seniors have even a tougher one. Wrap around seat bk adjustable
