When it comes to driving, eating, partying,big meets, L2B, or any "Big Mini Event", the UK crowd shows up by the hundreds, if not thousands, in Classic Mini's.
I've got a couple Modern MINI issues around the house, and yes, performance and shows would probably be there 1st priorities. Buying this off the shelf at $10.95/issue could be a bit of a strain, subs are probably near $150. or more/year? I used to get a sub of MINI WORLD, but had to let that run out when it approached $198./year.

I can't justify that much for reading material that hasn't got at least something naked in it

The fund raising events are so well covered in MINI WORLD (Classics) I believe the new MINI crowd is more into a completely different avenue. That said, looking for a sister club is still a capitol idea. I'd be very interested to see who would like to become family with us yanks.
