I didn't order the panoramic roof and am wondering if that's a big enough mistake to try to put In a change. My thinking was that I usually drive with my sunroof cover closed due to cold in the winter and because of noise. We have cold winters and hit summers. I had nothing but problems with my BMW 525xi sunroof. I was never satisfied with the noise level either. Plus my $50,000 car was already pushing near $80,000 and I didn't want to go another $1,500. In any event, have I made a grave mistake? And even if I have, what's the chances of a change now?
