"This type of roof was perhaps most popular in Germany in the 1930s, and is often called a \"Webasto\" since a German company of that name has been the main supplier for both factory built, and aftermarket, cloth car roofs since that time. This roof was used on many older cars such as the Mercedes-Benz Ponton, Saab 92, Citro\u00EBn 2CV, Fiat 500, GAZ-M20 Pobeda and the Fuldamobil. Nash Rambler was available as a cabrio coach, but they called it \"convertible landau\"."@en . . . . "yes"@en . . . "Cabrio coach"@en . . . . "December 2009"@en . .

A variant in which the original car/sedan's fixed rear glass window was retained first appeared in the 1930s, and had the advantage that it could be more easily retrofitted to an existing car; it was a factory option (although listed as a separate model) for the Volkswagen Beetle up to 1963. Some more modern cars also feature this roof style, for instance BMW 318ti, Volkswagen Polo, Nissan Figaro, Isuzu Amigo, Jeep Liberty and Suzuki Vitara."@en .
