I have a black 2000 Z3 Coupe 3.0i. I've loved it since the day I bought it - new! Since then I've always wondered why they didn't put a sunroof in this car! I have a moonroof that I hate because it's not a sunroof yet the BMW dealerships tell me I can't put a sunroof in this car. It seems to me if I already have a moonroof - what 's the big deal in converted it to a sunroof. Can anyone give me the technical reasons why this can't be done. I think if I can get a sunroof or a t-roof or something that will open up the roof - I'll literally feel like I'm riding on cloud nine.
