Well, the 4 is a tad smaller than the 6, which imo, makes it perhaps to big and heavy these days.
And it's "above" the 3 regarding branding, but it looks to much like a 3 imo.
The 2 is the driver car of these two, and the 4 is the GT, then why the 6?!
We need a SL killer from BMW imo.
I just hope the 2 isn't as short and therefor as tall as the 1 coupe was, it looked great, but it was just to tall imo.
But clearly, the M2 is the new M3, we're talking about E46 size here.
And of all the 3's i've owned, that's my favorite!
