Something tells me someone's going to have to Photoshop some larger diameter rims on this car. I didn't like the S-Class either when it first came out & then I saw the Brabus version sitting at Fletcher Jones Mercedes in Newport Beach. Filling up those wheel wells made a night & day difference.
Maybe that's what they're going for here. IMO German carmakers tend to think of the aftermarket arena & mild to moderate modders/tuners at the time of design. Well at least more so than domestic & Asian carmakers.
