I think it looks ok. The headlights are meh and the front bumper I am not entirely sure on..
But the new kidneys I like, the rear lights I like.
For me it's more about the tech, and I do wish mine had the new dash display and iDrive. Who knows how long my current iDrive will stay updated by BMW. I also wouldn't kick the M8 Comp suspension out of bed, if it is better.
If I could swap mine out for the new one at $0 or even a few grand I would, but it's a series of nice small changes that certainly don't justify giving my current M5 comp up, at least not for me.
I might... MIGHT.. call my sales lady and throw a hypothetical situation at her though
