when i was doing the club stuff it was a case of "if you put up bunting and flags and stuff" then you had to have cover, but if it was just cars stood on a field you didn't

can't remember who we used but it was around £140 for a year, but this was several years ago so prices may have gone up and rules might have been changed but it's at least a starting point as to what to expect

think that covered us for something like £1,000,000 personal injury to any spectators but not for the cars on the stand or owners crashing into each other
