I had a similar problem with my mirror recently and because it is so dangerous to driver without your side view mirror, I called the main dealer to get a new mirror but they didn't have any in stock! I couldn't believe it! I had to go to a glass company and get some mirror cut to tape to the mirror. Incidentally, I had my NCT the same week (and the genuine mirror still hadn't come in) and I still passed my NCT! With a piece of mirror taped onto the old mirror! Def. not complaining!
