Question: What General Motors car model name used by Buick for a line of upscale performance cars from 1936 to 1942 and 1954 to 1958, and from 1973 to 2005 for a mid-size car, can be described as a scraper?
Context: A brougham was a car body style based on the earlier brougham carriage.  Similar in style to the later town car, the brougham style was used on chauffeur-driven petrol and electric cars.  Electric broughams in the United States later evolved, becoming owner-driven cars without the outside seat for the chauffeur, but they kept the "brougham" name.  By World War II the original meaning of the term "brougham" had been largely forgotten, with American manufacturers using the term to denote a more luxurious trim level on a fully enclosed car.  General Motors has since used the term as a model name several times, while manufacturers in the United States have often used the term as a trim package designation. The Ranger was a General Motors car brand which lasted from 1968 to 1978.  Used in three main markets, the original automobile was marketed as "South Africa's Own Car" and was built in Port Elizabeth, South Africa, from 1968 to 1973.  The European model range was sold in two main markets, Belgium and Switzerland.  It was produced by General Motors Continental SA from 1970 to 1978 in Antwerp, Belgium.  General Motors Suisse SA in Biel-Bienne, Switzerland, also produced Rangers from 1970 until that factory's closure in August 1975.  A few Rangers were also sold in the Netherlands, perhaps to overcome some lingering resistance to German brands. The Chevrolet Opala was a Brazilian mid-size car sold under the Chevrolet brand in South America from 1969 to 1992, by General Motors do Brasil.  It was derived from the German Opel Rekord Series C, Opel Commodore Series A, but used USA-sourced engines and Holden styling.  Two four-cylinder engines: the Chevrolet 153ci 4-cylinder from Chevy II/Nova, which later got a new crankshaft stroke and cylinder bore, changing its size to 151ci (usually mistaken for the Pontiac Iron Duke engine), and the six-cylinder 250 from the contemporary line of North American car/light truck production.  GM manufactured about one million units including the Opala sedan, Opala Coupé, and the station wagon variant, the Opala Caravan.  It was replaced by the Chevrolet Omega in 1992, also an Opel spinoff.  It was the first passenger car built by GM in Brazil by the General Motors do Brasil division.  A luxury version of the Opala was marketed as the Chevrolet Diplomata. The Buick LeSabre is a full-size car made by General Motors from 1959-2005.  Prior to 1959, this position had been retained by the full-size Buick Special model (1936–58); in 1959 the LeSabre replaced the Special, a nameplate that was reintroduced in 1961 for Buick's line of compact cars.  The name originated with the 1951 GM Le Sabre show car designed by Harley Earl; that car is often mistakenly attributed to the Buick division, but in fact it was presented as a GM vehicle without reference to a specific GM division.  Buick closely related their 1956-1957 models to the GM LeSabre by replicating the top section of the rear wing into their design. .  The word "LeSabre" is French for sabre. The Grand Prix was a line of automobiles produced by the Pontiac Division of General Motors from 1962 through 2002.  First introduced as part of Pontiac's full-size car model offering for the 1962 model year, the marque varied repeatedly in size, luxury, and performance during its lifespan.  Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the 2nd generation to the 5th generation for the sedan and from the 2nd generation to the 6th generation from the coupe; it returned to a full-size car from the 6th generation to the 7th generation for the sedan, positioned below the larger Bonneville in Pontiac's model lineup. Buick Century is the model name used by Buick for a line of upscale performance cars from 1936 to 1942 and 1954 to 1958, and from 1973 to 2005 for a mid-size car. Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM).  Louis Chevrolet and ousted General Motors founder William C. Durant started the company on November 3, 1911 as the Chevrolet Motor Car Company.  Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918 and propelled himself back to the GM presidency.  After Durant's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose," would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929. A scraper is an informal term to describe a modified American-made luxury/family car, usually a General Motors model from the 1980s to current vehicles, typically enhanced with after-market rims.  Scrapers are popular in the San Francisco Bay Area of Northern California, usually associated with the hyphy music and lifestyle movement.  An example of hyphy is shown in the E-40 lyrics "sittin' in my scraper watching Oakland gone wild".  A scraper is a general description and can refer to a number of different model cars.  Popular models include the Buick Regal and LeSabre, Pontiac Bonneville, Buick Century, Oldsmobile Delta 88, Buick Riviera, Buick Reatta, Oldsmobile Cutlass Ciera, Oldsmobile Cutlass Supreme, Pontiac Grand Prix, Lexus SC, Chevrolet Caprice Classic, and Chevrolet Impalas, as well as full size conversion vans such as the GMC Vandura.  Supercharged automobiles are particularly sought after due to their high performance. Sunmobile was a model of a solar-powered automobile.  William G. Cobb of the General Motors Corporation built and demonstrated his 15-inch long model at the 1955 General Motors car show in Chicago on August 31, 1955.  The automobile was a futuristic miniature representation to show the possibilities of solar energy.  Since it was a miniature model, it could not be driven by a person. Buick ( ), formally the Buick Motor Division, is an upscale automobile brand of the American manufacturer General Motors (GM).  It has the distinction of being the oldest active American marque of automobile, and was the company that established General Motors in 1908.  Before the establishment of General Motors, GM founder William C. Durant had served as Buick's general manager and major investor.  Buick also has the distinction of being the first automobile maker in the world to equip its cars with overhead valve engines, which it did starting in 1904.
