19. 1969 Ford Mustang GT Cobra Jet
Ford’s best-selling pony car Mustang got its third restyling for 1969 and grew in size. The new body was bigger and wider. However, the wheelbase stayed the same. All three body styles were present, and buyers could choose between the elegant convertible, standard coupe, and sporty-looking Sportsroof fastback. The Cobra Jet 428 was available in all three body styles and with the GT package (via Mustang Attitude).

As expected, most were installed in coupes of Sportsroofs. But 122 people ordered the mighty Cobra Jets and Super Cobra Jets in convertible body style. Out of that number, the rarest is the Q-code Super Cobra Jet without the GT package with a manual transmission. Only five of these were built. Ford noticed that the GT package was losing its appeal since, at that moment, there were several much more attractive models in its lineup. Newly introduced Mach I, Shelby, and Boss models stole the spotlight from the GT. After 1969, the GT was gone.
