well to do that here would be impossible because of the insurance cover that would be needed, it would cost a fortune.
why would you need insurance cover on a racetrack? In the US road racing usually just means a track with corners in both directions as opposed to an oval.
I haven't heard of clapped out old car endurance type races here in new zealand, but we do have jallopy racing - more or less the same thing but with shorter races. usually held on a dirt speedway track. usually have a few races and then the last race at the end of the night is a demolition derby.
