Typically, this is a problem that the 05-07 stangs had. In 08, Ford began installing a piece of felt on both sides of the track to keep from scratching glass/tint. I have an 08, my gf has an 09 and we have both noticed one or two faint vertical scratches running the height of the window. What gives? Is it possible the felt just became dirty over time and scratched it? I do run with my windows down more often than not.
