Between 1969 and 1975, Zagato built the Junior Z based on the Alfa Romeo Junior Spider 1300 with a body designed by Ercole Spada. More aerodynamic, lighter and generally sportier, the small GT was intended to encourage sports drivers who wanted to reach their destination quickly on public roads to buy it. However, due to its relatively high price, this was not entirely successful, and the subsequent 1.6-liter version in 1972 did nothing to change this. The low number of units makes it a sought-after collector's vehicle today. This report traces the roots and characteristics of the Alfa Romeo Junior Z, showing the car in historical and contemporary photos and in the original sales literature of the time.
