I already posted this but here is how it should have looked to match the CS Concept roofline:
Then it would have been fantastic...
But something is wrong on the series model, it looks more "hunched" than the CS Concept which ironically is closer to the A7 profile but doesn't look hunched like the A7! Thanks BMW for spoiling what would have been an utterly magnificent 4 door coupé. It still looks good but does not match the design standard it could and should have reached.
