Iso Rivolta and Bizzarrini SpA
Società Autostar developed cars for Iso Rivolta including the Iso Rivolta IR300 and the Iso Grifo.
A dispute between Bizzarrini and Iso Rivolta ended their collaboration, and led to Società Autostar building variants of the Iso Grifo under the Bizzarrini marque. This led Bizzarrini to change the name of Società Autostar first, in 1964, to Società Prototipi Bizzarrini and then in 1966 to Bizzarrini SpA. The Società Prototipi Bizzarrini was declared bankrupt in 1969, which ended Bizzarrini's days as an automobile manufacturer.
Bizzarrini SpA also developed advanced designs for other companies, including American Motors for which they built prototypes for the AMX/3 project, and as style and technical consultant for GM in Europe and USA, top Japanese motorcycle marques and well-known designers such as Pininfarina.
