If a coupe is too inhibiting, taking the roof off in a convertible might be the freedom you’re after. Many open-top cars are variants of fixed-roof coupes and come with tops that can be retracted. Affordable convertibles include cars like the fun-to-drive Mazda Miata and Ford Mustang, the latter of which is a popular rental car. Premium sports cars like the Chevrolet Corvette and Porsche 911 and Boxster are also offered as convertibles and deliver impressive performance. Depending on the automaker making the convertible, you may see them also referred to as drop-top, roadster, spider, spyder, and cabriolet.
