Driving with it down would be a bad idea, but it would be great for when your parked with your stereo blastin'... I always thought the rear side windows should open like the way they open on mini-vans, know what i mean?? Or a sunroof that opens the entire length of the roof (not sure if that exsists already??)Yeah, I figured that would be a problem, but I wouldnt drive with it down, take it to shows, and put the window down?? haha.
