I have to day that i agree with a lot of the sentiments expressed regarding some of the big, Ford only shows. In general I've found them poorly organised and containing very little of interest for me, and won't be attending any more for the foreseeable future.
I'm leaning toward the mixed shows these days, which offer so much more variety.
WIth that in mind, I think a 3dr stand at something like Silverstone Classic would be a great thing to try and organise
