Good idea!
On the mustang, it has the short drop glass I mentioned. It's actually the best winter car I've ever had, believe it or not. The only problem I have with it in the winter is the 1/3" the glass needs to drop in order to get the door open. If it was parked in the sun, or the interior was warm when I parked it, and snow landed on it and melted. If I was gone a couple of hours or so, it will have frozen by the time I get back that seam where the glass rolls down. Then it's like one solid piece. Ugh.
