Interesting. The kink in the side fender leading into the door was mocked up almost a year or so ago, it was a blue convertible mock up with a girl driving it, same profile as the convertible, think it was a autobild mock up from a while back, but really surprised how close that mock up got. Mind you that line it right off the new 6 series, but still.
A mini 6 series.
Edit: found it. It was May 2011.
