Fascinating documentary.
In those days sedan class racing was more interesting because cars had different engine / drivetrain configurations:
- Front engine, front-wheel drive (Mini Cooper S)
- Front engine, rear-wheel drive (Ford Escort, Toyota Corolla)
- Rear engine, rear-wheel drive (VW Beetle, VW Dune Buggy)

. Probably a safety vehicle.
At 18:54 Dune Buggy
At 18:57 Mini Cooper S with checkered flag
At 19:11 More Dune Buggies

I wish the documentary gave more details about who won in which cars.
