I had been told in the past by someone who is involved with classic racing alot, that the "Cox" wasn't able to race in anything apart from future classics series or race series that only run 70's gt cars

Today I was at the Race Retro Show at Stoneleigh, where I was having a chat with the head scrutineer, who said "I have no problem to have a COX come and race with us in the Swinging sixties race series, I know some Cox history and have no issues except that they must be 10inch wheels with no wheel arch extensions"

It would be great to see the Triple C Cox out on track kicking MIni Butt
