The Vetta Ventura brochure and owner's manual. Only 19 produced

After the production of the Apollo, Intermeccanica then supplied the bodies to a firm in Texas, which used them to make a car called the Vetta Ventura.

Production of the Apollo was resumed in 1964 but this venture was dead by the following year. In all 88 Apollos were made, together with 19 Vetta Venturas, and is considered a "Texas Apollo". This car is not to be confused with the Warrior, made about the same time, in the same city, by a company with a similar name. 19 vehicles were produced.
