text: Inbuilt sunroof systems have a panel which slides between the metal roof and interior headliner, requiring some loss of headroom but providing a full opening in the roof. All inbuilts slide inside the roof, while some also include a rear venting feature (see pop-up) or express open/close functions. Inbuilts do not fit every vehicle, as the panel must slide and store completely within the vehicle roof. Historically, inbuilts were a metal sunroof panel painted to match the vehicle roof, but now most are glass-panel systems with sliding sunshades (typically referred to as moonroofs). One of the first examples was the 1960 Ford Thunderbird.
  Folding sunroofs (often called rag-tops or cabrio coach) are a European tradition. They offer the convenience of a sunroof, with an opening more like a convertible. The panel is made of fabric (often vinyl), which folds back as it slides open. After a long absence in European and North American markets, folding sunroofs have experienced a resurgence with several new factory-installed options. Aftermarket versions were once only manual, but now are also available in powered versions. Examples include the original VW Beetle, Renault Twingo and Jeep Liberty.
  Top-mount sliding sunroofs (rail mount topslider) have been a popular factory option in Europe for many years. A large glass panel slides open in tracks on top of the roof, with no loss of headroom. Most feature an integral wind deflector to eliminate wind noise. Examples include Donmar's original Skyroof topslider (aftermarket system), the London Taxi and Renault 5 cars.
