Ford-Mustang-Mk1-16[3]

From late 1961 into mid-1962, Ford designers tried out a wide range of themes for a sporty coupe based on the platform of the new Falcon compact. Each design was given an internal name for the purpose of discussion. One fastback design actually went through at least three different names starting with Avventura before moving on to Avanti and finally Allegro.The fastback design was originally sketched with a hatchback and rear-facing second row seat. While this car never made it to production, a variation of the fastback profile was eventually adopted as the third bodystyle for Mustang.
