That blue MSport is very cool.
The one thing some of the BMW forums posters had noted and didn't particularly like was that the F30 hood opens back of the badge, and doesn't include the entire front to the kidney grills, ie. there is a noticable hood line in the front. Might be less prominant in the "real", rather than in photos. Not a real biggie.
Yeah, when I first saw the new 5 series and then the spy pics of the new 3-series showing that line, I thought, "Oh no!" I really didn't like it. But now I've had time to get used to it, it doesn't seem bad to me now.
I also still think, as nice and aggressive as the front of the new 3-er looks, there's something awkward in its profile, a bit like its face was squished in or something (like a 5-series was squished into a 3 series). I find it most noticeable in profile view.
I also don't like the new M Sport steering wheel. Why couldn't they make it like the new X3 M Sport steering wheel? - that's perfect.
But I know from experience, I'm going to like it more over time. And overall, I think it's a good-great looking design.
The spy pics of the new M3 sedan looks like it has slightly better proportions. (People micro-analyzing and blowing up comparison shots of the front, for instance, show there is a difference)
