 I've got a new S550 sedan.  Mostly I'm pleased.  However, the fit of the right passenger door wood alignment is off about a half inch.  The drivers seat is hard and poorly cushioned.  Ergonomically, the steering wheel heater switch is invisible and not displayed.  Finally, the Eco mode won't stay off and resets to "on" every time the car is started.  Picky, picky, but for $120 thousand, I expect things perfect.
