1. Sunroof: Looks nice (pics on Prius Chat) but I wonder if driving with it open will mess with MPG as well?

2. My Prius is the coolest car ever. Nothing makes me swell with pride more than having someone come up and say something like "Oh, I've heard of these, they look so neat! How do you like it?" or having someone puropsely match my speed to check out my car as I'm driving around town. It's a real blast. I hated driving until we bought it.
