Mustangs are built in one place: the Flat Rock Assembly Plant in Michigan. Of the 500 pony-cars that role off the line every shift, five percent are randomly picked to undergo a test-track evaluation. Enter Vaughn Gittin, Jr., the pro drifting champion who competes in the Formula D series in a modified Mustang sponsored by Monster Energy. For whatever reason (who are we to question such hoonery?) he was brought to the plant's testing grounds with one assignment: drive the wheels off a new Mustang.
