 My wife and I both have 2005 mustangs and both have some of the same problems. Both cd players skip and will not play the cd at times. Both had to have rear windows replaced because they distorted the view out of them. Both have a harmonic vibration in the exhaust system that ford has no fix for it, the one that I drive has a noisy rear end {gear noise}. So much for improving quality. Ford seems to think sell cars the heck with quality.
