5. 1958 Aston Martin DB4
Be honest, if you saw one of these coming up beside you in traffic, you’d expect to find James Bond at the wheel. Just over 1,200 of these were produced between 1958-1963, and it holds the distinction of being the first Aston built outside of Italy at the company’s new place in Buckinghamshire, England. The limited number and that 240-horsepower engine make it a highly-sought after collectible, approaching seven figures.
