History of the Saab 93
Built between 1956-1959, the Saab 93 was the first Saab to be sold outside of Sweden. There were several different models, the main difference between them being stylistic; the 93B featuring a two-piece windshield instead of the one-piece and the 93F had front-hinged doors from a Saab GT750. It would eventually be replaced by the Saab 96, though the 93F would be sold alongside this for a short time.
