If you are referring to Incarnation as one of the shows it's not that serious at all. You only have to look at some of the cars there last year in the Ford club. There was a 1999 Focus with his plastic hubs painted pink and that was the extent of his show car. Nobody will be remotely interested in inspecting your rims or anything else that closely. Its chance to catch up with friends and park on Brighton seafront free of charge all day.. Don't expect to win any big trophies of cash prizes either...
