Gunnar Olsson, a driving force in Swedish motor racing during the 1940’s and 1950’s establishing the first permanent motor racing track in Sweden, home-built the “Go-On II” around Jaguar SS and Alfa Romeo 6C components

The car was built on a home-built frame and was fitted with Jaguar SS differential/axle, radiator and wheels. The gearbox was sourced from the Alfa Romeo 6C and this was probably installed with the Alfa Romeo 2.5 liter engine when Olsson replaced the Lancia unit.

The bodywork of the “Go-On II” was made by professional coachbuilder Svedbergs and it appears to have been styled after the Alfetta 158 voiturette.
