Thanks to everyone for your comments! We were not specifically looking for a color or finish, though I am partial to satin finish. We asked the installer to recommend colors that "pop" and I used the new Range Rover release color as an example of what we like. The ceramic coat was provided as standard with the wrap and is there for protection and ease of cleaning more than anything.
A few people have recommended blacking-out the wheel and windows as much as possible, which I tend to agree with.
Since color attraction is subjective, I won't opine. For the uniqueness you have created, its 5 Star. Congratulations - 50 shades of gray and away. BTW, my car is Jet Black Metallic, so my $$$ is not where my mouth is .
