Between 1969 and 1971, Pininfarina designed a total of three vehicles on two 33 Stradale chassis:  The Alfa Romeo P33 Roadster of 1968 was an open vehicle with a lower windscreen and a striking, contrast-painted roll bar. The vehicle used in the chassis No. 750.33.108. It was presented to the public at the Turin Motor Show in November 1968. Its whereabouts are unclear. Possibly the body of the P 33 was removed after the public exhibition, and the chassis re-bodied two years later to produce the Cuneo. The Alfa Romeo 33/2 Coupé Speciale of 1969, also known as Alfa Romeo 33.2, is a Pininfarina designed concept car, first presented at the Paris Motor Show in 1969. This 2-door coupé was designed by Leonardo Fioravanti, then working at Pininfarina; the design was influenced by the Ferrari 250 P5 concept shown a year earlier at Geneva. The 33.2 featured hydraulically working butterfly doors and pop-up headlights. It is based on the 33 Stradale chassis No. 750.33.115. It bore a striking yellow paint. The Pininfarina Cuneo was an open, wedge-designed sports car that was presented at the Brussels Motor Show in January 1971 and probably also based on the chassis No. 750.33.108. Italdesign Giugiaro presented the Iguana at the Turin Motor Show in November 1969. It is a closed two-seater sports coupé with an unusually high hedge on the basis of the chassis No. 750.33.116. The design showed some new elements, that Giugiaro few years later introduced in production vehicle designs. Thus, the body of the Iguana was made of brushed steel, this concept Giugiaro realized later when DMC DeLorean. The front end of the Iguana Giugiaro quoted in his designs for Maserati models Bora and Merak, and the rear end with the high-mounted tail lights were put into production in the Alfa Romeo Alfasud Sprint. Allegedly, a serial production of the Iguana was planned, the intention never realized, however.
