Seats are incredibly comfortable. Acceleration very good. Gas mileage around 20mpg. Extremely quiet. Ventilated seats overrated. Some features a bit complex. Best car I've ever driven. Test drove the MB500S and like the Lexus and its features/engineering/price much better.
The centralized contol screen for the climate control, sound system, navigation is neat but takes a while to learn.
Voice commands are beyond me, as is the programming features on the navigation and door locks. Also, cruise control will not work in bad weather for safety reasons (no override for the laser/radar detection mechanism).
