What component forms the rear sides of an automobile?

The component that forms the rear sides of an automobile is the quarter panels. These are the sections of the vehicle's body that extend from the rear of the car’s doors to the back of the vehicle. Quarter panels are crucial because they house various components, such as the taillights, and help to provide structural integrity and aesthetic appeal to the automobile. They can also influence the aerodynamics of the vehicle. Understanding the function and placement of quarter panels is essential for appraisers, especially when assessing damage or making repairs in automotive services.
