what is the purpose of sunroof in car
An automotive sunroof is a movable (typically glass) panel that is operable to uncover an opening in an automobile roof, which allows light and / or fresh air to enter the passenger compartment. Sunroofs are either manually operated or motor driven, and are available in many shapes, sizes and styles. While the term sunroof is now used generically to describe any glass panel in the roof, the term "moonroof" was historically used to describe stationary glass panes rigidly mounted in the roof panel over the passenger compartment.
