 A cabriolet version called the Gran Sport comprised most of the Daina Series cars.The Gran Sport had a steel body with an aluminum hood designed by Stabilimenti Farina (3 all aluminum bodied Gran Sports were made as well) but when they closed in 1953, Bertone took over production with a coupe model of their own design called the "Sport".Following the Amica, Siata introduced the 300BC Barchetta Sport Spider in 1951.
