The Cord 810, and later Cord 812, was an luxury automobile produced by the Cord Automobile division of the Auburn Automobile Company in 1936 and 1937.
 It was the first American-designed and built front wheel drive car with independent front suspension.
 It followed the 1934 Citroën Traction Avant and the Cord L-29, both of which also had front wheel drive.
 Both models were also the first to offer hidden headlights.
The Abbott-Detroit was an American luxury automobile manufactured between 1909 and 1919.
 It was considered powerful and well-designed, and had a Continental engine.
 Production of the auto began in Detroit, Michigan and was moved to Cleveland, Ohio in 1916 at which time the automobile name was shortened to Abbott.
 The cars were guaranteed for life by 1913, when electric lighting and starting had been standardized.
Cadillac , formally the Cadillac Motor Car Division, is a division of the U.S.-based General Motors (GM) that markets luxury vehicles worldwide.
 Its primary markets are the United States, Canada, and China, but Cadillac-branded vehicles are distributed in 34 additional markets worldwide.
 Historically, Cadillac automobiles have always held a place at the top of the luxury field within the United States.

The Zil-111 was a limousine produced by the Soviet car manufacturer ZiL in 1958–1967.
 It was the first post-war limousine designed in the Soviet Union.
 After tests with the shortlived prototype ZIL-Moscow in 1956, which gained a place in the Guinness Book of Records as the largest passenger car in the world, the ZIL-111 was introduced from "ZIL" in 1958.
 The body style was in the American tradition of the time and resembled the mid-1950s cars built by Packard, an American luxury automobile manufacturer, although, apart from the similar styling, the car was an original design and had nothing in common with them, except in general layout.
 The interiors were trimmed with top quality leather and broadcloth and decorated with thick pile carpet and polished wooden fittings.
 It featured a comprehensive ventilation and heating system and a 5-band radio, all of which could be controlled from the rear, electric windows, vacuum-operated screen wash, windshield and front door window defrosting.
 It was powered by a 6.0 L V8 engine producing 200 hp connected to an automatic transmission (similar to that of Chrysler's PowerFlite and influenced by it, but different in design) giving a top speed of 170 km/h , hydraulic drum brakes with a vacuum servo booster, coil and wishbone IFS.
 The car won a top prize at the Brussels Expo World Fair in 1958.

The GAZ Chaika (Russian: Ча́йка ), which means gull, is a luxury automobile from the Soviet Union made by GAZ ("Gorkovsky Avtomobilny Zavod", translated as Gorky Automobile Plant (Russian: "ГАЗ" or "Го́рьковский автомоби́льный заво́д")).
 The vehicle is one step down from the ZIL-111 limousine.
 Chaika production consisted of two generations, the M13 of 1959 to 1981 and the M14 of 1977 to 1988.
Delahaye 134 is a four-cylinder luxury automobile manufactured by Delahaye.
 Based on Jean François' Delahaye 135, it was produced from 1933 to 1940 (from 1936 as the 134N) and was briefly brought back by Delahaye manager Charles Weiffenbach in 1945 after hostilities ended.
 At the same time, the larger engined 134G also appeared.
 As a part of the ""Plan Pons"" aimed at reviving French industry, Delahaye was to focus on building luxury cars, in particular for the export markets.
 The lesser 134 did not suit the plan and was taken out of production by 1946, in preference to the more lucrative 135, 148, and 175 models.
 Most 134s built carried saloon bodywork by Autobineau, a subsidiary of Letourneur et Marchand.
The Packard Clipper is an automobile which was built by the Packard Motor Car Company (and by the later Studebaker-Packard Corporation) for models years 1941 to 1942, 1946 to 1947 and 1953 to 1957.

 The Clipper was introduced in April, 1941, as a mid-model year entry.
 It was available only as a four-door sedan.
 The Clipper name was reintroduced in 1953 for the automaker's lowest-priced lineup.
 By 1955, the Clipper models were seen as diluting Packard's marketing as a luxury automobile marque.
 It was named for a type of sailing ship, called a clipper.

 On September 24, 1991, three days after he had last been seen alive leaving his house in the Boston suburb of Revere, his body, bound, beaten and stabbed, was found in the trunk of his Cadillac a short distance away.
 The killing remains unsolved.
