They offer a unique fusion of sensations that elevate the driving adventure thanks to their ability to seamlessly blend driving thrills with an open-air experience.

Those equipped with four-cylinder engines stand out as some of the cheapest convertible cars on the market. Yet, they still manage to maintain their fun-filled charm by adding the open-air experience to their lightweight and agile package.
