The Siata Amica was the company's first production model being produced between 1948 and 1952.

It was powered by a Fiat 500cc engine capable of producing 22 horsepower. A 750cc unit was also available, raising horsepower slightly, to 25. Production of the Amica began in 1948 and continued through 1952. There were two bodystyles available, a two-seater convertible/spider and a coupe.

In 1948, a specially prepared Amica won the Italian Championship. The car was outfitted with an engine that produced a little over 40 horsepower and was mated to a five-speed manual gearbox.
