I'll be there, not having missed one since 1985... 800-mile round trip but hey-ho.
Back then there was nothing wedge-based and very little for even my early 60's 100E. It was very much pre-war parts and ephemera but none the worse for that.
Now, I'd recommend it to anyone for a day out (or two if you want to see everything properly). The vast range on offer has to be seen to be believed, notwithstanding the cars for sale and the contents of the car parks.
Over the years I've picked up everything from a TR7 dhc hood frame to TR8 brochures via orginal "Triumph" showroom number plates.
Go on, it's worth it...
