I found this very good amateur video of the 1984 Fuji Gran Championship at Fuji International Speedway where a bunch of Sunny B110s, Sunny B310s, Starlet KP61s and first generations Honda Civics battled the TSA class 250km race. The competition is fierce and you can enjoy an 8 minutes spectacle of bumps, spins and drifts:
BTW: at 3:37 an unidentified car is going through the corner on 3 wheels. Anyone got an idea what car it is?
