I don`t like the fake lightbar either, nor do I like the graphic in the taillights of the E. They look like triangle emergency vehicle hazard indicators.
The dashboard with the surfboard theme is obviously Jaguar S-Type inspired. I can add that to my dislike list with the HVAC vents.
As a package though the E has the 5er beat IMO. Its the small details that make the E look more sleek, understated, and sophisticated.
The rear glass panel for example with the rounded corners looks like it is molded into the bodywork on the E. The same can be said for the 3/4 window into the C-Pillar. The 5er with its squared-off rear glass panel already looks dated and will not age well in the years to come.
