After the war they made a couple of Alfa Romeo 6C 2500SS, (Fiat 6C 1500cc) Lancia Aprilia based cars and for the 1947 Villa d'Este a Fiat 500 barchetta.

Colli made one very special prototype in 1946, the Aerauto PL.5C roadable aircraft. From the 1950s it worked with Alfa Romeo making cars such as the 6C 3000CM and its own single variant of Disco Volante. The company also converted Alfa Romeo Giuliettas and Giulias into estate cars in the 1960s. In 1955 Colli constructed the very shortly used Arzani-Volpini Formula One car utilising a twin-supercharged Maserati 1500 inline-four engine.
