12. Apollo 3500 GT
This car falls under several names, including the Vetta Ventura and Griffith GT. But the project started as the Apollo 3500. It was the brainchild of the Californian engineer, Milt Brown. He wanted to build a proper sports car to rival those European exotics. With the help of the Italian company, Intermeccanica, the Apollo project took shape in the form of a handsome coupe with a 3.5-liter Buick V8.
They later moved the production to Texas and renamed the Vetta Ventura, but the car stayed basically the same. The bodies were shaped in Italy and then sent to America. However, it got an upgraded engine in the form of the 4.9-liter Buick V8. Production started in 1962 and lasted until 1965. However, some reports say they completed the last examples in the early `70s. In the end, they only built 90 cars.
Although the Apollo 3500 was a proper sports car with 240 HP from its V8 engine and a lightweight, it was a capable coupe with great perspective. But, the production problems, high price and the unknown company became too big of a problem to overcome.
