This often meant that a driver who chose the right class could win the overall championship without any chance of overall race wins , thereby devaluing the title for the spectators – for example , in the 1980s Chris Hodgetts won two overall titles in a small Toyota Corolla prepared by Hughes Of Beaconsfield , at that time a Mercedes-Benz/Toyota main dealer when most of the race wins were going to much larger cars ; and while the Ford Sierra Cosworth RS500s were playing at the front of the field , Frank Sytner took a title in a Class B BMW M3 and John Cleland 's first title was won in a small Class C Vauxhall Astra.
The Ford Sierra Cosworth RS500s was winning at the British Touring Car Championship when Frank Sytner took the title in a Class B BMW M3 .
