Hardtop convertibles provide the exhilaration of roofless driving combined with the security and comfort of a conventional car. When the weather is perfect, you can drop the top to enjoy the sunshine, wind, and panoramic views. If it's too hot, rainy, or you're just up for a quieter ride, you can bring the hardtop up in seconds. The hardtop advantage is that it's typically more insulated and secure than a soft top, resulting in a quieter ride and better protection from the elements and potential theft. Some of the most popular hardtop convertibles include the BMW 4 series, Mercedes-Benz SLC, and Mazda MX-5 RF.
