Haha yeah. Sunroof adds 40 pounds. DCT adds 40 pounds. I got a 6MT = No additional weight
Either way you will have some regret I suppose, but the fact that my car is black, and will see 99% road time means I will use my moonie more than a carbon roof.
BUT, having said that, if I have of chosen any other colour that wasn't black I would have got the CF roof without hesitation.
