Chiti and Bizzarrini built, with sponsorship from the Scuderia Serenissima's Count Giovanni Volpi, a road-going sports car and a Formula One car.
In 1967, Bizzarrini rebodied at least one V-8 as a coupe and sold it to the Duke of Aosta (it is known as the Duca d’Aosta coupe).
After leaving Ferrari, in 1961 Giotto Bizzarrini set up “Prototipi Bizzarrini” in Livorno, Tuscany where he designed and consulted for marques like ATS, Lamborghini and Iso Rivolta.
Diomante resides in Nichelino, Italy and operates Autocostruzioni S.D., where he keeps parts, special tools and original moulds from Bizzarrini P538s and Bizzarrini 5300s.
