Ford’s own paperwork undersold this 1969 Mustang GT the moment it left the factory. The 428 Cobra Jet carried an official 335-horsepower rating that engineers knew was fiction, chosen to keep the car out of the insurance industry’s crosshairs. Add a convertible body, a rare Indian Fire paint code, and a factory power top, and you have a combination Ford built fewer than thirty times. The registry that tracks them can confirm four survivors.
