Dubbed “the world’s smartest car” before smart cars were a thing, the Nash Metropolitan (1953-1961) was a quirky marvel. Available as a hardtop or convertible, this pint-sized wonder was an American brainchild produced by the Brits. With a wheelbase shorter than a VW Beetle, it aimed to be the perfect second car for those who believed bigger was better. It was as nimble as a cat in a parking lot—a sub-compact charmer with a flair for style and economy in a land of gas-guzzling giants.
