Yep, DJ is right. Most dealers will contract their sunroof work out. The factory GTZ sunroof is an expensive puppy and most of the money is in labor. I was told $900 here in Maryland. They have to take headliner down and install the pocket and controls for the factory model. That seems to be what drives up the cost. I would make sure that wherever you take it, they know what they're doing.
