Before it was the Britsh Touring Car Championship, it was the Saloon Car Championship. The regs in place were FIA Group 2 and the field was diverse. Very diverse. Just check out what Crystal Palace looked like back in 1971.
Britain in 1985 was wild. Thatcher was in charge, the Battle of Beanfield took place, the Sinclair C5 both entered and exited production, and Group B rally cars tore up Wales in one of the most sensational showings in rally history.
