1978 I did the "End of season race" at Hockenheim.
This race was a lot of fun, because the cars are sorted out for the classes by weight/horspower.
I raced against all different kind of cars, like VW Scirocco, BMW 2002Tii, Renault R5 Alpine, Opel Manta, Renault Alpine 1600, etc.
I was able to finish with a 3rd
place out of over 20 cars.
This racing was with normal street cars and on street tires.
Below is the trophy for that 3rd place
