The IZh 2125 "Kombi" (Russian: ИЖ-2125 Комби, short for "combination") is a compact car produced by the Soviet car manufacturer IZh from 1973 to 1997.
 It was based on an Izhevsk-modified Moskvitch 412, with the first prototype released in 1972 as a small family car.
 It was considered to be the first Soviet hatchback (released about a decade before the well-known Lada Samara), though the car actually possesses a station wagon body wherein the "D" pillar has its own support and does not gain from weight reduction (which would position the model more in the liftback family).
 In Russian literature the car is referred to as liftback.
 For the same reason, the car was given the "Kombi" nickname, which in a way alludes to the Combi coupé (the word "kombi" itself meaning "station wagon" in German and Polish, while in Russian a station wagon is called "universal").
An automobile model (or car model or model of car, and typically abbreviated to just "model") is a particular brand of vehicle sold under a marque by a manufacturer, usually within a range of models, usually of different sizes or capabilities.
 From an engineering point of view, a particular car model is usually defined and/or constrained by the use of a particular car chassis/bodywork combination or the same monocoque, although sometimes this is not the case, and the model represents a marketing segment.
The BET 500 was light car model developed by BET, a small Greek vehicle manufacturer.
 Introduced in 1973, it used a Fiat 500cc engine, had a metal body and seated up to five passengers.
 It was certified for production and 15 were built and sold, of which one survives to this date in excellent condition.
 Although the car featured good road handling for a 3-wheeler and was roomy for its size, it could find few buyers at these, more prosperous times for Greece, while the company could not secure agreements with banks for favorable loans to potential buyers.
 Petros Konstantinou, owner of "BET", hoped to sell the production rights to other countries; according to him, there were talks with a South African company involving plans for exports or transfer of production to that country, but they were never realized.
 Another planned version, the "BET 600" was not built and the company ceased production altogether in 1975.
The Mercedes-Benz S-Class, formerly known as Sonderklasse (German for "special class", abbreviated as "S-Klasse"), is a series of luxury flagship vehicles produced by the German automaker Mercedes-Benz, a division of German company Daimler AG.
 The S-Class designation for top-of-the-line Mercedes-Benz models was officially introduced in 1972 with the W116, and has remained in use ever since.
The Ford flathead V8 (often called simply the Ford flathead, flathead Ford, or flatty when the context is implicit, such as in hot-rodding) is a V8 engine of the valve-in-block type designed by the Ford Motor Company and built by Ford and various licensees.
 During the engine's first decade of production, when overhead-valve engines were rare, it was usually known simply as the Ford V‑8, and the first car model in which it was installed, the Model 18, was (and still is) often called simply the "Ford V‑8", after its new engine.
 Although the V8 configuration was not new when the Ford V8 was introduced in 1932, the latter was a market first in the respect that it made an 8-cylinder affordable and a V engine affordable to the emerging mass market consumer for the first time.
 It was the first independently designed and built V8 engine produced by Ford for mass production, and it ranks as one of the company's most important developments.
 A fascination with ever-more-powerful engines was perhaps the most salient aspect of the American car and truck market for a half century, from 1923 until 1973.
 The Ford flathead V8 was perfectly in tune with the cultural moment of its introduction, leading the way into a future of which the Ford company was a principal architect.
 Thus it became a phenomenal success.
 The engine design, with various changes but no major ones, was installed in Ford passenger cars and trucks until 1953, making the engine's 21-year production run for the U.S. consumer market longer than the 19-year run of the Ford Model T engine for that market.
 The engine was on Ward's list of the 10 best engines of the 20th century.
 It was a staple of hot rodders in the 1950s, and it remains famous in the classic car hobbies even today, despite the huge variety of other popular V8s that followed.
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.
The R42 is a New York City Subway car model built between 1969 and 1970 by the St. Louis Car Company in St. Louis, Missouri for the (IND/BMT) B Division.
 It was the last 60 ft B Division car built for the New York City Subway until the R143 in 2001, and the last car model class to be built in married pairs.

The Ferrari TR, or 250 Testa Rossa, is a race car model built by Ferrari in the 1950s and 1960s.
 They were introduced at the end of the 1957 season in preparation for the regulations restricting sports cars to 3 litres for Le Mans and World Sports Car Championship races from 1958.
 These cars dominated their competitors, with variations winning 10 World Sports Car Championship races including the 24 Hours of Le Mans in 1958, 1960, and 1961, the Sebring 12 Hours in 1958, 1959 and 1961, the Targa Florio in 1958, the Buenos Aires 1000Km in 1958 and 1960 and the Pescara 4 Hours in 1961.
 These results led to World Sports Car Championship titles in 1958, 1960 and 1961 with only the Aston Martin DBR1 defeating the Testa Rossa at the Nurburgring in 1958 and at Le Mans, the Nurburgring and Tourist Trophy and the World Championship in 1959.
 They were closely related to the rest of the Ferrari 250 line, including the 250 GTO.
Biotechnia Ellinikon Trikyklon (Βιοτεχνία Ελληνικών Τρίκυκλων, "Greek Three-Wheeler Manufacturer"), or BET, was a small vehicle manufacturer founded in Athens by Petros Konstantinou.
 It was one of several manufacturers - the first appearing in the early 1940s - that converted BMW or other motorcycles into light utility three-wheelers.
 In 1965 it entirely designed and built a small five-seat passenger car with a BMW 125cc motorcycle engine.
 Although the type was certified, only one was built due to problems in availability of parts for further production.
 Following this design, three-wheeled truck models were developed and produced.
 A second passenger car model was designed and introduced in 1973, known as model "500", with a Fiat 500cc engine.
 With metal body, seating up to five passengers and featuring very good road handling, it was a rather advanced three-wheeler for its time.
 It was certified for production and 15 were built, of which one survives to this date in excellent condition.
 There were even talks with a South African company involving plans for exports or even transfer of production to that country, but they were never realized.
 The company ceased production in 1975.
