1974 - Saab Catherina - Like the Saab Formula Junior and the Saab Sonett Super Sport (Sonett I) the Catherina began life as the personal sports car project of Sixten Sason. Sason conducted freelance work but was soon commissioned by Saab to adapt his design for full scale production. Work on this commenced in January 1963 and by May work began on the assembly of a prototype at the Svenska Järnvagsverkstäderna (ASJ) workshops in Katrineholm (hence the car's name).
