Racing Numbers:
My understanding is that race numbers on road cars are fine.
E.g. In London, Foxtons the estate agents have a fleet of minis with numbers on the sides.
I think the black line through the numbers relates to road legal racing cars on the road.
But this is their own "in house" rules trying to encourage a better public image.
E.g. Rally cars driving between stages.
But as always, what do I know?
Cheers, Paul.
PS
Mr T - Do you come back to find a crowd around the car?
