Just remember that (at least in the 05-09 cars) there's a pony dot matrix behind your rear view mirror that won't be on the replacement since the replacement glass probably won't be an OEM part.
It will be there if you ask for OEM glass.
I've been lucky enough to have had my original windshield get popped with a BB gun from a previous neighbor (assumption based on several reasons), and my current/replacement windshield looks identical to the original one
