text: A sunroof is a movable panel that opens to uncover a window in an automobile roof, allowing light and fresh air to enter the passenger compartment. Sunroofs can be 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 moveable 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. A moonroof has a glass panel that is transparent and usually tinted. Previous terms include sunshine roof, sliding head, and sliding roof.
  History
  A common configuration for early automobiles included a fixed roof for the rear passenger compartment and an uncovered section for the chauffeur in a style known as Coupe de Ville, Sedanca (two door) or Sedanca de Ville. An open cabin allowed the driver to be more connected to their surroundings, demonstrated that the car's owner employed a paid driver (one reason chauffeurs wore uniform) and identified the owner through the driver's livery (the other reason for the uniform). Road speeds were increasing and vehicles were changing from occasional use to full-time transport meaning that they were increasingly being used in bad weather. In order to provide better shelter for the driver therefore, temporary cover was now demanded. These part-time roofs, sometimes at first just a stretched piece of leather, became more sophisticated comprising frame elements and leather or water-resistant cloth to form the construction, and installations even included spaces provided to store the parts when not in use.
