You could order the CX edition G11 and a bunch of them were in khi with a manual sunroof, the G100 had powered electric glass roof. (Which was a royal pain in the ass to own due to it leaking into the A pillars as the factory drains were made of chewing gum type rubber).
A lot of those cars were swapped for a solid roof due to that as it would literally flood the car in a light rain.
