The previous owner put an aftermarket sunroof in my alero and it is a POS! There are no water leaks, only a high pitch whine like a kettle when I drive faster than 60KPH. It is not adjustable or identifiable, so I am still working on a remedy.
If you must have a sunroof, find a reputable installer, and spend the money to do it right! Take my situation as a example of "You get what you pay for"
If it were me I'd be happy without a sunroof.
I do not have any names on hand, but there are some good companies that have near OEM type sunroofs available.
Good luck with your search! let us know how you make out!
