Context paragraphs:
Toyota Progrès: Toyota Progrès (pronounced "Prog-Ray") is a Toyota midsize luxury sedan which was sold in Japan from May 1998 to June 2007, replacing the Toyota Corona EXiV.  The engine which the Toyota Progrès used is an inline 6-cylinder of 2.5L or 3.0L with VVT-I.  Since April 2001 Toyota put in Progres direct injection (D4) engines 1JZ-FSE (2.5L) and 2JZ-FSE (3.0L).  It was exclusive to Toyota Japan dealerships "Toyopet Store", while its twin the Brevis was exclusive to "Toyota Store" locations, and shared a marketing approach used on the "Toyota Vista Store" alternative, called the Toyota Verossa.  The width and engine displacement exceed Japanese Government regulations concerning exterior dimensions and engine displacement, and therefore it classified in the larger "passenger car" tax bracket.  Two engine sizes were offered to allow Japanese buyers which annual road tax they were willing to pay; the larger engine did offer higher levels of standard equipment and luxury features.

Buick Straight-8 engine: The Buick Straight-8 engine (Fireball 8) was produced from 1931 to 1953 and sold in Buick automobiles, replacing the Buick Straight-6 engine across the board in all models in 1931.  Like many American automobile makers, Buick adopted the straight-8 engine in 1931 as a more powerful alternative to the previous engines.  However, unlike most other car makers at the time, Buick had been using a valve-in-head/OHV overhead valve design or I-head since its inception and continued this practice in their inline-8 designs.  The engine was sold in different displacements depending on the model of car and the year and was constructed upon two distinct (possibly more) block castings.  The smaller displacement versions internally resembled the inline Chevrolet straight six, with additional cylinders.  The large block version (the 345 and 320, used in large-chassis models such as the "Roadmaster") was considerably heavier and this weight adversely affected vehicle performance and handling.  In earlier years the engines used cast-in-place bearings that were then machined, which made engine rebuilding an expensive procedure, but after 1937 they began using drop-in bearings.  The last year for Buick's straight-8 was 1953, but only in the Special, as the new V8 322ci Nailhead became standard in all other lines in the same basic chassis.  Starting in 1954, the Special received the V-8 as well.

Buick Gran Sport: The Gran Sport name has been used on several high-performance cars built by Buick since 1965.  In the GM brands hierarchy, Buick was surpassed in luxury and comfort appointments only by Cadillac, which did not produce performance models.  As a result, the Buick GS series were the most opulently equipped GM sport models of their era.

T-Type: The T-Type is a series of Buick automobiles that were popular during the 1980s.  This marketing approach for Buick products was a revival of a similar approach used in the 1960s (and later revived in the 1990s) with the Buick GS designation.

Alismatid monocots: Alismatid monocots (alismatids, "basal monocots") is an informal name for a group of early branching (hence basal) monocots, consisting of two orders, the Acorales and Alismatales.  The name has also been used to refer to the Alismatales alone.  Monocots are frequently treated as three informal groupings based on their branching from ancestral monocots and shared characteristics: alismatid monocots, lilioid monocots (the five other non-commelenid monocots) and commelinid monocots.  Research at the Royal Botanical Gardens, Kew is organised into two teams I: Alismatids and Lilioids and II: Commelinids.  A similar approach is taken by Judd in his Plant systematics.  They also organise their monocot research into two teams I: Alismatids and Lilioids, and II: Commelinids.  A similar approach is taken by Judd in his "Plant systematics".

Scraper (car): 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.

Lexus LF: The Lexus LF line is a series of concept cars built by Lexus, the luxury vehicle division of Toyota Motor Corporation.  The "LF" designation refers to "Lexus Future".  The LF Series vehicles features coupes/convertibles, including: the LF-A, the LF-A Roadster, LF-LC, LF-CC, and the LF-C; sedans: the LF-S, LF-Sh, and LF-Gh; crossover SUVs: the LF-X and LF-Xh; and hatchbacks: the LF-Ch.  The first concept vehicle of the LF Series, the LF-X, appeared in 2003.  The LF Series utilizes L-finesse, a design philosophy named for "Leading Edge" and "finesse", which debuted on the LF Series concepts and later extended to all new production Lexus vehicles.  New vehicle technologies on the LF Series include advanced instrumentation, multiple driver-selected vehicle configurations, hybrid and experimental powertrains, and unconventional driver interface designs.  The vehicles also feature new design cues which derive from the L-finesse design language of "Intriguing Elegance" (純), "Incisive Simplicity" (妙), and "Seamless Anticipation" (予).  Several of the LF concept vehicles have appeared close to their production counterparts, while the design cues of other LF concepts appeared on more distinctly different production vehicles.

Pimpmobile: A pimpmobile is a large luxury vehicle, usually a 1960s, '70s or '80s-model Lincoln, Cadillac, Buick or Chrysler vehicle, that has been customized in a garish, extravagant and kitsch or campy style.  The style is largely an American phenomenon.  Aftermarket features or modifications such as headlight covers, hood ornaments, expensive stereo systems, unusual paint colors, and shag carpet interiors were used by car owners to advertise their wealth and importance.  Once considered a pejorative, these customized vehicles were popular with pimps, drug dealers, and gang leaders in the ghettos of large cities of the United States in the late 1960s, 1970s and 1980s, especially New York City, Kansas City, Chicago, Oakland and Los Angeles as a symbol of their wealth and power.  By the 1990s and 2000s, pimpmobiles included any large, extravagantly customized vehicle, such as a customized SUV truck.

WiLL: The WiLL brand was a marketing approach shared by a small group of Japanese companies who decided to offer products and services that focused on a younger demographic from August 1999 until July 2004 in Japan.  The companies that participated were the Kao Corporation (a manufacturer of personal hygiene, household detergents, and cosmetics), Toyota, Asahi Breweries, Panasonic, , Ezaki Glico Candy, and (an office furniture and stationery manufacturer).  Toyota also engaged in a similar "youth oriented" approach in North America, with the Project Genesis program.  This selective marketing experiment reflected a Japanese engineering philosophy called Kansei engineering, which was used by other Japanese companies.  All products were listed online at "willshop.com".

Buick Limited: The Buick Limited was an automobile built by Buick between 1936 and 1942 and during model year 1958.  Since 1959 Buick has used the "Limited" name to denote those models which featured a high level of trim and standard options in its various model ranges.
