American automobile industry in the 1950s
In 1954, the smaller American Motors Corporation (AMC) was formed when Hudson merged with Nash-Kelvinator Corporation in a deal worth almost USD $200 million ($1.735 billion in 2013 dollars) the largest corporate merger in U.S. history at that time. Other mergers with smaller independent manufacturers followed. Although AMC was moderately successful it was never sufficiently large to challenge any of the Big Three, and was eventually bought by Chrysler in 1987.
Motorette Corporation
The Motorette Corporation was an automaker based in Buffalo, New York from 1945 to 1948. It was noted for manufacturing the Motorette, a three-wheeled miniature vehicle which was marketed as a compact auxiliary alternative to standard cars in more heavily congested areas in the years following World War II, with about 6,000 being produced and sold across the United States, Asia, and Latin America.
