24. Triumph Spitfire
The Spitfire was the second definitive British roadster from the 1960s. Despite having similar mechanics, similarly modest power and performance, Spitfire got its name from the World War II fighter plane. This legendary roadster was introduced in 1962. It was powered by a diminutive 1.1-liter four-cylinder engine producing 63 HP (via Auto Express).
Over the years, the power grew to a 1.5-liter engine with 71 HP and more torque, improving the driving dynamics. Like other British roadsters, the biggest market was the US. Out of 314,000 made, most of them ended up in America. This means the Spitfire is easy to come by and relatively inexpensive to buy. Decent examples cost below $10,000. For $15,000, you can find perfect late models.
