Car and Driver review added to the original post.
While they do say that the car is an improvement, there are many details lacking about how the car drives in particular, the review read more like a brochure from BMW rather than someone who had driven it on the road and track, and comments on steering feel (a necessity in any C/D BMW review) were avoided twice in the article which is strange as even in the X7, C/D doesn't hold back on their feelings about BMW's numb steering of their cars.
