That the original Alfa Romeo Giulietta was a subcompact automobile manufactured by the Italian car maker Alfa Romeo from 1954 to 1965. The Giulietta was introduced at the Turin Motor Show in 1954 and almost 132000 were built in the Portello factory in Milan.

The first Giulietta model was a coupé, the Giulietta Sprint, introduced in late 1954. This was followed by a saloon in spring 1955 and in mid 1955, the open two-seat Giulietta Spider, featuring convertible bodywork by Pininfarina. In 1957 the most powerful version, called Giulietta TI (Turismo Internazionale) was presented with minor cosmetic changes to the hood, the dial lights and rear lamps.

Carrozzeria Colli also made the Giulietta station wagon variant called Giulietta Promiscua. 91 examples of this version were built. Carrozzeria Boneschi also made a few station wagon examples called Weekendina.
