I don't know if this has come up before, but how about a carbon fiber sunroof? I would think there are people who have moonroofs (the only way to get ABS on the XD I think) and don't appreciate having like 20lbs of glass at the very top of the car. Myself, I like the slide/tilt functionality just fine, but it doesn't have to be transparent even. It could be Lexan or just CF. I'm pretty cheap but it would be tempting depending on price, and I thought I'd throw it out there. Not to mention the moonroof has to be one of the simplest shapes imaginable and would be easy to ship. How much could it possibly cost, carbonman?
