The exterior of a car refers to its outer surface and design, which includes elements like the body shape, paint color, and materials used. Common materials for car exteriors include steel, aluminum, and plastic, which contribute to the vehicle's durability and aesthetics. The design can vary widely, from sleek and sporty to rugged and utilitarian, depending on the car's intended use. Key components of car exteriors include the hood, doors, windows, and bumpers. These parts not only enhance the car's appearance but also serve functional purposes, such as protecting passengers and internal components. Additionally, features like headlights and taillights are essential for visibility and safety on the road.
