A very brief career for this Czechoslovakian Wartburg powered car, it was constructed by Vladimir Valenta who hailed from Brno. The Mustang finished 8th in 1964 and 10th in 1965 at the Sachsenring amongst quite good quality fields on both occasions, it also won a race at Stramberk in 1964, the strength of the field is not known.
