The Alfa Romeo Giulietta (Tipo 750 and Tipo 101, meaning "Type 750" and "Type 101") is a family of automobiles made by Italian car manufacturer Alfa Romeo from 1954 until 1965 which included a 2+2 coupé, four-door saloon, estate, spider, Sprint, and Sprint Speciale. The 2+2 was Alfa Romeo's first successful foray into the 1.3-litre class. From 1954 to 1965 a total of 177,690 Giuliettas were made, the great majority in saloon (Berlina), Sprint coupé, or Spider body styles, but also as Sprint Speciale and Sprint Zagato coupés, and the rare Promiscua estate. The Giulietta series was succeeded by the Giulia in 1962.

The ALFA 24 HP is 4.1-litre four-cylinder passenger car, the first model produced by Italian car manufacturer ALFA (Anonima Lombarda Fabbrica Automobili), which in 1919 would become Alfa Romeo. It was introduced in 1910, the year ALFA was founded, and produced until 1914 in ALFA's Portello factory near Milan. The model's name comes from its tax horsepower rating, then frequently used as vehicle designation. The 24 HP was commercially successful and continued to be developed for a decade. In 1914 some updates transformed the 24 HP into the ALFA 20-30 HP, produced in 1914 and 1915—with some hundred cars assembled after the war in 1920. In turn the 20-30 HP evolved into the 1921–22 Alfa Romeo 20-30 ES Sport, the first car to be badged Alfa Romeo from its introduction. In total the 24 HP and 20-30 HP were produced in 680 examples.
