The Triumph 1800 refers to models from the British car maker that made use of the 1776-cubic inch, straight-four engine. One such car was the Triumph 1800 Town and Country, a sedan made from 1946 to 1949. They also made an 1800 version of the Roadster, which was made from 1946 to 1948 and based on the 1800 sedan. Around 1948, Triumph 1800 models were replaced by 2000s, those cars that had a slightly larger engine. Today, any early 1800 from Triumph is a desirable collectible, especially for those who like imports. To find one for your collection, turn to the listings at FossilCars.
