Buick Centurion
Visually the Centurion was nearly identical to the Buick LeSabre (lacking the portholes usually found on the LeSabre), but used the 455 in³ big-block V-8 and five-spoke "mag" wheels from the Buick Riviera GS. Body styles included two-door and four-door hardtops, and a very rare convertible.
Less than 10,000 units convertible units were manufactured during the three model years of production.
Total Centurion production was around 110,000 units; the Buick Centurion Registry has the total production numbers for all three model years.

Buick Electra
The Buick Electra and the Buick Electra 225 were full-size premium automobiles built by the Buick division of General Motors. The Electra name (in various manners) was used by Buick between 1959 and 1990. All Electra 225s were hardtops in the 1971 to 1973 model years, eliminating the previous 4-door pillared sedan variant and the convertible. In 1974 Buick adopted GM's pillared coupe body and fitted it with the "Landau" option on the Electra Limited coupe; in 1975, all Electra 225 coupes had fixed rear side windows and center posts. The 4 door models remained hardtops until the 1977 model. Starting in 1974, the Limited model didn't have any Electra 225 badges on it and there was a new Park Avenue option package available on the "Limited" 4 door hardtop in 1975.The 1975 Buick Electra 225 Limited was the longest 4-door hardtop car GM ever built. At 233.4 inches it was even longer than the 1975 Cadillac DeVille; its last Fleetwood 4-door hardtop had been in 1964. The model also ushered in a return of the six window configuration that Buick offered between 1959 and 1964.

Buick LaCrosse
The Buick LaCrosse is a Buick automobile model introduced in the United States for the 2005 model year. It is a mid-size sedan and replaces the previous Buick Century and Buick Regal models. It uses an updated version of the GM W platform, featuring a V6 engine and front wheel drive. The LaCrosse features a GM 4T65-E transmission and a 3.8 L 3800 V6 as well as a 3.6 L HFV6 V6.

Buick Estate Wagon
The first estate wagon was first offered on the 1940 Super model. It used a wooden body and was available on Buick's larger "C" series (Super and Roadmaster) in the 1946-53 model years. Then it was offered the smaller "B" body Special, Century, LeSabre and Invicta with all steel bodies from 1954 to 1964. It was reintroduced on the "B" body again in 1970 and was simply called Estate Wagon until 1977. Then it was available as LeSabre Estate Wagon or Electra Estate Wagon. The last Estates were rear wheel drive B-bodies with a 115.9 in wheelbase. The Electra Estate model name was used in 1988 and 1989 even though the Electra sedan used the front wheel drive C platform. The final year of Estate production, 1990, just used the Estate model name. The Estate was replaced with the B-body Roadmaster Wagon that same year.

Buick LeSabre
The Buick LeSabre was a full-size car made by the Buick division of General Motors. For many years, the LeSabre was considered the entry level full-sized Buick, carrying the lowest base price in the Buick lineup. Prior to 1959, that position had been held by the full-size Buick Special model; in 1959 the LeSabre replaced the Special, a nameplate that was reintroduced in 1961 for Buick's line of compact cars.

Buick Limited
The Buick Limited was an automobile built by the Buick Motor Division of General Motors, Flint, Michigan (USA) between 1936 — 1942 and during model year 1958. Since 1959 Buick has the "Limited" name to denote those models which featured a high level of trim and standard options in its various model ranges.

Buick Luxus
Luxus was a trim level used on the 1973-74 Buick Century and 1974 Buick LeSabre. It was the equivalent of the "Custom" trim used on other Buick models in 1974-74 and on the equivalent 1965-1973 and 1975-1978 LeSabre model and on the 1968-1972 Skylark and 1975-1978 Century.

Buick Lucerne
The Buick Lucerne is a full-size automobile sold by the Buick division of General Motors that replaces the Park Avenue and the LeSabre in 2006. Although the rear wheel drive GM Zeta platform was considered, the production Lucerne introduced at the Chicago Auto Show on February 9, 2005, is a front wheel drive derivative of the G-body Buick LeSabre. Initial sales of the Lucerne have been strong, with the car claiming 24% of the full-size sedan market in the United States.

Buick Park Avenue
The Park Avenue was Buick's flagship sedan. A luxury trim level, the Ultra (1991), was also available throughout the Park Avenue's run. The Buick Park Avenue Ultra luxury sedan featured a more powerful 205-240 hp supercharged V6 that became standard in 1992 versus the regular 170-205 hp V6. Prices for the Park Avenue ranged from $34,705 for the regular Park Avenue and $39,225 for the Ultra luxury trim.

Buick Rendezvous
The Buick Rendezvous, introduced in the spring of 2001 as a 2002 model year vehicle and produced through the present, is a sport utility vehicle produced by the Buick division of General Motors. The Rendezvous (and Rainier) will be replaced by a new crossover SUV, the Enclave, on the GM Lambda platform for 2008.

Buick Somerset
The Buick Somerset was a 2-door coupe produced by the Buick division of General Motors between 1985 and 1987. Buick had previously used the "Somerset" name as a trim-level package on the Buick Regal in the early 1980s. The Somerset was one of a number of down-sized cars built on GM's N platform. Destined to replace the Buick Skylark, the Somerset name badge failed to resonate with the buying public. Initially launched as the Somerset Regal in 1985, the name was shortened to Somerset in 1986, when a sedan version of the car was added under the Skylark name (Buick's strategy of using the Skylark badge is not new — this trend occurred in 1975 when the 2-door coupe based on the Chevrolet Nova was badged the Skylark while the 4-door sedans were known as the Apollo). Starting in 1988, the Somerset name was discontinued, and all models were called Skylark. The Somerset did not do as well in the marketplace as the Pontiac Grand Am which was based on the same platform. The Somerset did have some interesting features such as an all digital instrument cluster and a surprisingly luxurious interior despite its small size.

Buick Wildcat
The Buick Wildcat was a full-size automobile produced by the Buick Division of General Motors from 1962 to 1970. For its first year, the Wildcat was a variation on the Buick Le Sabre / Buick Invicta that mated the smaller full-size two-door hardtop Buick body (known as the "sport coupe," body production code 4647) with a high-performance 325-horsepower version of the 401ci Nailhead V8, known as the Wildcat 445 for producing 445 ft·lbf of torque. To further distance itself from the Invicta, the Wildcat also included a bucket seat interior with a center console, special exterior side trim, vinyl-covered roof, and its own unique emblem: a stylized head of a wild cat, located on each of the C pillars. However, the Wildcat did share the Le Sabre's and Invicta's trio of portholes on the front fenders..., a design cue lasting only through the 1963 model year. From 1963 to 1970 the Wildcat was its own series, no longer a subseries of the Invicta. Wildcats built starting in the 1964 model year did not have the traditional portholes, but instead had chrome hash-marks on the lower front quarter panel immediately behind the front wheel housings. The Wildcat line was superseded by the Buick Centurion in 1971.
