context_page_description: The Buick Regal is an upscale mid-sized automobile that was first introduced by Buick for the 1973 model year. The model was originally positioned as a personal luxury car, and typically offered in both coupe and sedan forms until 1997, when the Regal became sedan-only due to the decline of the personal luxury coupe market. For certain model years between 1973 and 2004, the Regal shared bodies and powertrains with the similar Buick Century, although the Regal was positioned as a more upmarket vehicle.
  The Regal was discontinued in the North American market in 2004, being succeeded by the Buick LaCrosse. In 2008, a new version of the Regal was introduced for the Chinese market, which is a badge engineered version of the Opel Insignia. The new Regal was introduced to the North American market in 2011, positioned as a mid-size vehicle. A new model was introduced for 2018, which is offered in a liftback sedan and a "TourX" station wagon version. GM plans to discontinue the Regal in the North American market after the 2020 model year, making Buick exclusively a CUV marque there.
context_section_description: Buick had been the first GM division to bring a personal luxury car to market with its 1963 Riviera, but was otherwise slow to react to the developing lower-priced mid-size personal luxury market, which Pontiac created with the 1969 Grand Prix and Chevrolet with the Monte Carlo the following year, 1970. At the same time, Oldsmobile added a formal notchback coupé to its intermediate line, the Cutlass Supreme, in 1970 and that model soon became Olds' best selling intermediate. Buick did not get its own personal luxury coupe until the GM intermediates were redesigned in 1973, the so-called "Colonnade" cars that eliminated hardtop models completely. In a curious name swap, the Skylark name was dropped from Buick's intermediate line and instead the Century nameplate, last used in the 1950s, was revived for them.
  A highly trimmed, two-door coupe, the first Regal, officially marketed as the "Century Regal Colonnade Hardtop coupe", shared its front and rear styling with its Century parent with distinctions amounting to differing grilles and taillight lenses. The Regal shared the same "Colonnade" pillared hardtop roofline (a hardtop with B-pillars (center pillars) but frameless doors unlike a sedan body) and greenhouse (window area) with the Grand Prix, Monte Carlo, and Cutlass Supreme as well as the lower-priced Buick Century Luxus coupe. Like its corporate cousins, the Regal (and Luxus) featured the newly fashionable opera windows, which were small fixed rear-side windows surrounded by sheetmetal, instead of the traditional roll-down windows.
  For the first model year in 1973, the Regal nameplate was only used for Buick's version of the GM intermediate personal luxury coupe, but the following year gained a sedan companion (there was no Regal station wagon).
  Regal interiors were generally more luxurious than lesser Century models with woodgrain trim on dashboard and door panels, along with door-pull straps and bench seats with center armrests with cloth, velour, or vinyl upholstery. Optionally available throughout the run was a 60/40 split bench seat with armrest. For 1976 and 1977, the Regal coupe was available with the S/R option that included reclining bucket seats with corduroy upholstery.
  The model lasted five years with minimal changes, although there was a fairly substantial facelift in coupes for 1976 (sedans retained their original 1973 sheetmetal through 1977), which incorporated the recently-legalized rectangular headlights (horizontally mounted on coupes, and vertically on sedans—much like the mid-1960s Pontiacs). The Regal coupe sold reasonably well, although it lagged behind the Monte Carlo and Cutlass Supreme which had become the best-selling cars in America by 1976.
  The Regal was most commonly powered by Buick's 350 cu in (5.7 L) V8, which was standard equipment on all models for 1973 and 1974, and optional on coupes but standard on sedans from 1975 to 1977, and the larger 455 cu in (7.5 L) V8 was optional for 1973 and 1974 models only. Starting in 1975, Regal coupes came standard with Buick's resurrected 231 cu in (3.8 L) V6 engine previously offered on the 1964–1967 Skylark; the engine's tooling had been sold to Kaiser Motors for use in Jeep models (Kaiser was purchased by American Motors in 1970 and Jeep became an AMC division) and sold back to GM by AMC in 1974. For 1975 and 1976, the Century and Regal were the only mid-sized cars in America to offer V6 engines. The bolt pattern for this vehicle is 5×4 ³⁄₄ inches (120.7 mm).
  The Century designation was quietly dropped from the Regal for 1975.
