I completely agree on a contrasting color - added door handles and gas cap to the 16M and looking for a cf rear deck You have to look closely to see the cf on my mac which is why IMO it would look even better.
I'd say this is one of those issues that is very subjective and a matter of preference. I'm generally in the "don't like the look of CF" camp but can appreciate those that like it. I have seen it done well and can appreciate it even though it's not my cup of tea.
That said, the stark contrast of the hood without much more to the theme is akin to having the car just having a randomly different color, and, not my cup of tea.
But that's what's great, it is someone else's fancy, and if it makes them happy, good for them.
