Notable features include advanced infotainment through the MBUX system, a massive digital screen, and driver-assistance technologies that contribute to a safer driving experience.

I feel that the features listed for this vehicle is good. I just didnt see one option that would have made me buy the vehicle fast. I did not see the multi contour massage feature. I wished that it would have been made clear on the listing.
