Seeing the car in the show room and short test drives never tell the entire story. Once you drive it for a while you can start to understand what you like and dislike. It's been a week and driving this car and its absolutely wonderful. Beautiful comfortable interior, very comfortable seats many adjustments available, the voice control is easy to use and great for hands off computer controls, all 5 performance options are very useful for different places you are driving like city, highway mountains and smooth change on the fly. The extra power on the AMG is really incredible "F1 at my fingertips with the paddle shifters" after a few days I realized how useful the blind spot technology is it becomes second nature and just part of the normal driving safety. I feel I have a combo luxury car, sports car and SUV at my fingertips. Absolutely love it. Too soon to talk about reliability but if it's like the MB I owned before this it should be excellent.
