The Guanci SJJ was only produced in prototype form between 1979 and 1982 with the final prototype being completed in 1982; it never entered full production due to financial difficulties. Only three prototypes were ever created, with the last one finished in 1982.
The Guanci SJJ-1 was an obscure American sports car developed in the late 1970s by Jerry Guanci, an Illinois-based businessman with a passion for automobiles. The car was designed as a mid-engine GT with exotic styling inspired by European supercars of the era.
The car featured a spaceframe chassis with fiberglass bodywork. It was powered by a Chevrolet V8, providing a blend of American muscle and European styling. A manual gearbox, likely sourced from a Corvette or similar sports car. While exact figures are unclear, the car aimed to rival the likes of Ferrari and Lamborghini in terms of aesthetics and performance.
