Both are amazing. I'd be proud to own either car.

But purely from an aesthetic point of view, I'm not too crazy about the 6 series convertible top. I took a good look at one a couple of days ago, and it just doesn't look right to me with the top up.

But considering that BMW will release a convertible hardtop 3 series, perhaps a hardtop 6 is around the corner. Now that would be beautiful...
