no rs has ever come with a factory sunroof, moonroof, or anything other than a solid sheet of metal. the reason some people think adding one in is because it increases the weight of the car (glass weighs more than sheetmetal)........however, if you didn't buy the RS for its weight advantages, give a big finger up in the air to people who think you're stupid for adding something you like. Adding a sunroof adds about .000003% chassis flex....i.e. you'll never notice it on a street car. So for those who are *****ing about the addition of a sunroof/moonroof, setz dich hin und halt die schnautze (sit the f down and shut the f up). It's his car, let him do what he wants with it. Hopefully we were able to answer your question before the moron came in and was whining about what someone else was doing to a car that isn't his.
