We had a truly awful purchase experience at North Star Ford. Two months after purchasing a late-model used car from them, one of the rear proximity sensors fell out. North Star Ford refused to cover the repair costs even though we bought their touted "bumper-to-bumper" coverage. They would not replace the sensor (which they said was covered) without replacing the entire bumper cover (which they said wasn't covered since it was "cosmetic").
