I am waiting on my Package #9 and am contempating adding a sunroof. Has anybody out there done this and what did it do to your mileage?

there are grooves in the roof... you'll change the drag coefficient quite a bit...

I've seen a few posts on the yahoo 2004 Prius group about this. There are people having it done, but I haven't paid much attention to that topic.

I guess you would have to fit a small sunroof that fits between the groves. The shape of the roof (front to back) could be a problem as well.
