I bought my car with 4 miles on it and when I bought it I told the dealer that the driver's door front didn't match the front quarter 100% perfectly. It actually sits in probably a 1/16 of an inch. The dealer told me to remember that it is a Mustang and that most Mustangs aren't perfect off the assembly line. My other door is perfect. Do your doors match perfectly with your front quarter panel??? Maybe I'm just too picky but I had them write it up so they have to make adjustments if necessary. The dealer said there is a chance it could get worse if they mess with it.
