There's one in Denton that I see at lunch, driving around the University of North Texas.
It's 'hideous' to me, and better looking in the photographs.
I don't have a 'blueprint' of it, so I can't evaluate it's roofline.
This may have been the car which got the guy who signed off on styling fired. BMW spent $ 260-million to 'fix' the design.
Personally, I prefer the fastback coupe design because of the aero. They're turbulent-quiet and laminar-loud. Raging calmness. But I understand that many buyers have expectations about 3-row seating and gobs of interior room.
