I have had one. It was extremely noisy and after about 3 years rain started making its way into the body, I took it to the shop multiple times, replaced the gaskets, and it was only a temporary fix each time. (Nissan Altima) friends with sunroofs on other cars report similar problems.What's wrong with sunrooves?
Note: I've never had one so it's an honest question (I do, however, own a convertible that gets driven top down a lot).
