Guys, here's a video file taken from inside the car: 3l_GTV_windows_up_n_down.flv - Video - Photobucket - Video and Image Hosting

First with windows up, then from 25 seconds with them down (you'll hear the squeaky window ops: ).

It seems to sound a little deeper since that video was taken.

Oh yeah, the recording is made from my Sony camera hanging from the passenger headrest, so the video is terrible, and you can hear the camera knocking against the seat a bit, but thankfully the sound of the car is plenty loud enough
