Apollo 3500 GT
This car is known under several names, including Vetta Ventura and Griffith GT. However, the project started as Apollo 3500, and it was the brainchild of Californian engineer Milt Brown who wanted to build a proper sports car to rival the European exotics. With the help of Intermeccanica founder Frank Reisner, the Apollo project started to take shape in the form of a handsome coupe powered by a 3.5-liter Buick V8 (via Silodrome).
The production was later moved to Texas and renamed Vetta Ventura, but the car stayed the same. However, it got an upgraded engine in the form of a 4.9-liter Buick V8. Production started in 1962 and lasted until 1965.
