Sapphire black! We have one and the color is truly GORGEOUS!

Space gray is an awesome color and we actually planned to order that color but it has been used in nearly all of the advertisements and was the #1 color choice when we were ordering ours in mid-January (not sure if that's changed) so we decided against it.

The bamboo is VERY cool. It's unlike any other interior trim I've ever seen. However, the aluminum trim is very sleek and feels more "sporty". I guess it depends on what kind of look you are going for.
