I think if someone could spare the time to organise it then this idea is a REAL goer.
I'm sure none of us will mind if there is a sliught differential between cost price and sell price, to cover the hassle of organising it all (Ie bung 2-3 quid a ticket on and at least the cost of that persons own trip would be covered judging by the interest on the other thread)
I'd love to offer to help, but right now im just too busy - however - i will probably be freed up as Le-Mans draws closer, so may be able to make a useful contribution then....
