A convertible is a type of car that features a roof that can be either fully or partially retracted. This design allows drivers and passengers to enjoy an open-air experience when desired, making it popular for leisurely drives and warm weather. Convertibles come in various styles, including two-door and four-door models, and can be powered by different types of engines. The mechanism for opening and closing the roof can vary, with some convertibles using a manual process while others have automatic systems. Many modern convertibles are designed with enhanced safety features and structural integrity to ensure a secure ride, even when the roof is down.
