This is a Valiant P3, which appeared at a Supersport Race in Zandvoort, Holland in 1987. As year of build was given 1968, and it had a 1600 cc engine which did not want to run properly during the weekend making the car terribly slow. It was run by a German driver. I assume that it named P3 because of its resemblence to the Ferrari P3. Nowhere on the holy web I can find any info on this car.
