 The Mustang I made its formal debut at the United States Grand Prix in Watkins Glen, New York on October 7, 1962, where test driver and contemporary Formula One race driver Dan Gurney lapped the track in a demonstration of the prototype.He reportedly drove the car "to 120 ... causing the automotive rumor mill [to begin] churning even faster" with reports by "Motor Trend" that "Ford will produce a sports car to compete with the Corvette" which was exactly the publicity stunt Lee Iacocca was hoping to achieve.For the next two years, both Mustang Is appeared at car shows and automotive events as show cars.
