It's like a smaller ford fair. I wouldn't travel across the country for it but there's lots of fords parked up at castle Combe with people going on track.
You won't likely find mountune or Revo stands but there's usually car cleaning stands and the sort there to browse.
I enjoy it but I'm easily amused. When I got the date I added to my calender to take off work like you did but I've got a few things going on that I'm mostly writing off car shows this year. Ford fair will be my only one I think
