Wow! What a very well organised website, sounds such a great car event/meet.
I see from previous years since 2009 the Mazda MX5 does well at these meets, 422 attendance in total. But no Rover 75's at all, and only 1 ZT and just 71 MGF/TF's.
It looks like TVR's do well, also Porsche 911, quite a few clubs attend I see.
