Right im up for this, but seriously this is one HELL of a trek as I live in Gloucestershire. However, I did used to live in York so have plenty of friends willing to put me up for the night!
I defo think go down the chairty route with this. My mum used to be a charity event organiser so knows how to arrange big events like this and if we did do a charity you would end up with loads of media coverage. I can help with all that part of it if you like the idea. Imagine that as an iconic photo... would be around for a fare few years! I dont think we should exclue BMW minis unless you want to keep it as retro as possible...but not just because its a bmw. its for charity we could all just be nice to each other for once! lol
charity is a good idea, may aswell do sothing constructive while having fun! lol.

yeah, need all help can get really lol.
