The current situation is like standing on shifting sand. No-one really knows what'll happen next or where the path forward is. Everyone is simply trying to "make it work" and hoping things will become clearer at some point. Craig's example of the loom issue will be just one of a whole host of things. I sincerely hope the shows continue but as said earlier, it's a bit like a "classic kit car" display on the club stands and I think the traditional kit car builder is dying out. Lots of customers these days are monied and expect a high-quality product, and I can't see them (or at least, not many) heading off to a trad kit car show. If Grosvenor decide they can't make it work, then maybe the future will be for kit car companies to take space at the major car gatherings over the summer - Goodwood, Silverstone, NEC Classic Show maybe, that kind of thing. Probably expensive though, and it'll be passed on to customers one way or t'other.
Meanwhile, if you've got a desirable car (e.g. Strat rep of any sort), right now you're quids in. Look after it and you can't lose.
