I'm happy to have it because it is the best car I have ever owned. The interior is plush, glitzy, and a bit ostentatious, but this is required in a huge Mercedes-Benz Saloon car. The sat nav is intuitive, but the COMMAND system takes around a week to fully master. Driving this car is interesting. You feel the huge size, but the 4Matic system, just seems to make it feel smaller. The power is easily accessible an the torque can be accessed in the low rev range. The steering is good, for a huge saloon car, but it takes to many turns of the wheel. The paddle shifters on the side feel awkward and hard to use, they also feel cheap. Overall this car is probably the best car on the market today.
Interior, night vision is amazing, massaging seats, the feature that moves the sides of the chair during turns to keep you centered in your seat. Power is amazing when you put your foot down.
Steering takes to may turns to turn the car, paddle shifters feel cheap and aren't intuitive.
