AndyS : Ahh yes that Rover Metro Bodied 6R4, I had a hunt around and found info, so thanks for that.. I'll see if I can track down the owners/drivers as that is certainly spectacular.
In terms of the Berg Cup/Berg Rennen, Gruppe H is the class that has all the crazy aero and wild engine specs. The nearest event to the UK is in Eschdorf which is on May 3rd and 4th :

chunder : the GN J.A.P has always been a favourite of mine, the way that gets thrown into corners is amazing.
I fully agree on closed road hillclimb vs. our shorter technical hillclimbs, it would be great to have a spread of both. Is hard to do justice to something like a Pike Peak car when you are giving them a 30-40 second blast.
Alan : Thanks for the links, that has given me something to go on
