That new rendering above looks really nice. My main concern is the rear however, as I really think BMW screwed up the rear of the latest Z4 compared to the E85 which I think looks great (obviously lol). I had considered getting a newer Z4 a few years back, but decided against it as the rear just doesn't do it for me.
Fingers crossed BMW comes out with a winner here, or my Z4M Roady goes nowhere!
