IMO the problem with the RS7 is design. It's an ugly car!
The major design flaw IMO is the way the roofline joins with the trunk lid. From a lateral view, the roof/trunk lid line looks weird and fugly. It reminds me of one of the 90's iterations of the Ford Taurus.
There is a reason why in 3:51 min of video, there is not one clear lateral shot of the car showing said roof/trunk lid line.
The same reason why said line is hidden behind the guy speaking most of the time. In other takes, just when the camera is about to show said line, the video quickly gets edited into showing something else.
The word lateral is key here, there are shots of said roof/trunk lid line from other angles, but never lateral.
And I know taste varies, that's why all above is IMO only...
