In the programmes for the 1977 and '78 Swedish Grand Prix meetings there are details of a series for Camaros.
The 1977 Series was called the Puss & Kram Super Star Cup and seems to have been known as Kiss and Cuddle.
The 1978 Series was the Tretorn Camaro Cup and had a car, number 20, entered by the Kiwi Racing Team. Does anyone know anything about that team?
