I am a Challenger Owner-to-be and am a tad concerned with this as I live in Ohio... My brother lives here as well and has an 06 Mustang and does not have a garage. He doesn't really have any issues with this but he has seen some posts on the Mustang forum of Mustang owners complaining of this issue. I wish the windows had frames.... I am guessing this is a cost cutting thing. I think Chrysler got this technology from Mercedes as I have seen on another forum people discussing this issue and someone said a few Mercedes models have had this technology for some years now.
