Pontiac built several mockups of a “Ventura” compact car using Chevrolet’s upcoming rear-engined Corvair model. Ultimately, when they introduced their own compact for production as a 1961, it was instead called the Tempest and built on the traditional Buick Special / Oldsmobile F-85 platform. This mocked-up “Ventura” was photographed in the styling studio on April 6, 1959.
