I have rarely driven my Camaro with the top up since I got the thing, but I noticed yesterday that it is pretty hard to see out the rear window when I do have it up. Since I am in the market for a new top anyway I wanted to see if anyone here knew if it's possible to get a top with a glass window instead of the plastic one. If not, then what is a good alternative so I don't have to worry about the window getting all wavy?
