Question: What is a line of compact cars produced by Prince Motor Company in 1980 and discontinued in 1999?
Context: The Nissan Leopard is a line of luxury cars built by Japanese carmaker Nissan.  The Leopard began life in 1980 and was discontinued in 1999.  Leopards were initially based on the Japanese market Nissan Skyline and Nissan Laurel and the American Datsun 910/Nissan Maxima, then later based on the chassis of their Nissan Cedric and Nissan Gloria contemporaries and were rear wheel drive.  Final versions were the contributing factors to Nissan's Infiniti M and J products. The Prince Homer was a small commercial vehicle manufactured by the now integrated Prince Motor Company.  It was available as a van, called the Homy, a double cab, or regular cab truck.  The first model was known as the T64, and was sold as the Prince Homer or PMC T64.  The T640 was introduced in 1966 and was sold as a Nissan (without any modifications aside from badging) due to Prince merging with Nissan.  It was shared with the Nissan Cabstar which was sold at "Nissan Bluebird Store" Japanese dealerships.  Production of the T640 ended in 1968.  The Homer was exclusive to Japanese Nissan dealerships called "Nissan Prince Store", when Prince was merged with Nissan in 1966.  The Homer name was discontinued in 1982, while the Cabstar name remained when Nissan refocused "Nissan Prince Store" vehicles as private purchase products. The Nissan Skyline (Japanese: 日産・スカイライン "Nissan Sukairain") is a line of compact cars, sports cars and compact executive cars originally produced by the Prince Motor Company starting in 1957, and then by Nissan after the two companies merged in 1966.  After the merger, the Skyline and its larger counterpart, the Nissan Gloria, were sold in Japan at dealership sales channels called "Nissan Prince Shop." The Gloria (Japanese: ) is a large luxury car made from 1959 by the Prince Motor Company, and later by Nissan Motors since its merger with the former - hence being originally marketed as Prince Gloria and later as Nissan Gloria.  Initially based on the smaller Prince Skyline, the Gloria line was merged with Nissan Cedric starting with 1971 models and both continued until 2004, when they were both replaced by Nissan Fuga. The Ford CE14 platform was a front wheel drive automobile platform used by the Ford Motor Company for its compact cars during the 1980s and early 1990s.  The CE14 platform was heavily derived from the platform of the European Ford Escort.  A stretched variation of the CE14 appeared in 1984 for the mid-size Ford Tempo and Mercury Topaz. The Prince Motor Company was a Japanese automobile manufacturer from 1952 until its merger with Nissan in 1966.  Prince began as the Tachikawa Aircraft Company, a manufacturer of various airplanes for the Japanese Army in World War II, e.g., the Ki-36, Ki-55 and Ki-74.  Tachikawa Aircraft Company was dissolved after the war and the company took the name Fuji Precision Industries.  It diversified into automobiles, producing an electric car, the Tama, in 1946, named for the region the company originated in, Tama, using the Ohta series PC/PD platform.  The company changed its name to Prince in 1952 to honor Prince Akihito's formal investiture as Crown Prince.  In 1954 they changed their name back to Fuji Precision Industries, and in 1961 changed the name back again to Prince Motor Company.  In 1966, they became part of Nissan, while the Prince organization remained in existence inside Nissan, as "Nissan Prince Store" in Japan until Nissan consolidated the Prince dealership network into "Nissan Blue Stage" in 1999. The Saturn S-Series was a family of compact cars from the Saturn automobile company of General Motors.  This was the first series of Saturn vehicles.  The automobile platform, the Z-body, was developed entirely in-house at Saturn, and it shared very little with the rest of the General Motors model line.  It implemented a spaceframe design, which had been used on some Pontiacs during the 1980s.  This meant that the side panels did not carry load and could be made of plastic instead of metal.  These polymer panels were dent-resistant, something that remained a selling point for Saturn until just a few years before the Saturn brand was discontinued.  The S-series was sold from the fall of 1990 for the 1991 model year through the end of the 2002 model year.  Significant design updates were made in 1995, 1996, and 2000 for all cars, and the SC coupes were redesigned significantly in 1997.  Nearly every year of the S-Series' existence brought at least some minor changes to the architecture of the car. The Prince R380 was a racing car built in 1965 by Prince Motor Company to compete in the Japanese Grand Prix.  Following the merger of Prince Motor Company and Nissan Motors in 1966, the R380 was modified into the Nissan R380-II (also known as R380 Mk.II). The Prince Sedan was a Japanese compact executive car made from 1952 until 1957 by the Tama Motor Company (later renamed as the Prince Motor Company in November 1952), which was one of the successors of the Tachikawa Aircraft Company.  It was replaced by the first generation Prince Skyline ALSI in 1957. The Prince Skyway was a commercial delivery van and pickup produced by the Prince Motor Company from 1957 to 1967.  It was based on the various Prince Skyline models of the period.
