I know many have wondered about headroom loss to the power moonroof. In the Canadian specs, it appears that in front/rear the loss is 42 / 8 - I assume mm. Translated to US speak that would be about 1 2/3" front, 1/3" rear. They also get illuminated vanity mirrors for both the passenger and diver. Not sure about the driver - guess it's for those who live near large bodies of water!
