Happily spec'ed mine with a moonroof, that was a no-brainer for me, especially since it's at no-charge.
Love all the light, love cracking it for some outside air, and love opening it on occasion to let the air rush in, especially at night.
I did end up wrapping it in a carbon fiber wrap, something I didn't plan to do. But the CF wrap my shop had looked so authentic, I said, "Why not?", plus it goes with my CF theme (inside and out). The dealer thought I had cut the factory roof off and installed a real carbon fiber roof, around my moonroof.
Uh, no, sir, it's just a wrap.
