The Nash Metropolitan was sold from 1953 through until 1961.

I believe it was also sold as a Hudson when Nash and Hudson merged in the 1950s to form the AMC and later as a standalone marque during the Rambler years, as well as in the United Kingdom and other markets.

And talking of the UK, because of the tie in with the Austin Motor Company, who became involved with its production, many people here also refer to it as the Austin Nash Metropolitan.

Quite a complicated story for such a small car!
