Triumph Spitfire
The Spitfire was the definitive British sports roadster of the 1960s. Despite having similar mechanics, similar modest power, and performance, the Spitfire got its name from World War Two fighter plane and boosted a much more aggressive and sportier design with lower sides and a sharper front end (via Auto Express).

This legendary roadster was introduced in 1962 and powered by a pretty diminutive 1.1-liter four-cylinder engine with 63 HP. Over the years, the power grew to a 1.5-liter engine with 71 HP and more torque, improving the driving dynamics. Like all other British roadsters, the biggest market was the US, and from 314,000 made, most of them ended up here.
