Citroen is a French car manufacturer. Citroen was founded as a company in 1919. The Citroen brand is currently owned by the French company PSA which also manufactures cars under the brand Peugeot.
Citroen cars are not presently exported to the USA. Official export ended in 1973. Independent importers continued to supply some models for several years on. However, the present-day US regulations do not make it financially viable to import new Citroens to the US.
