Martini,
Yep, that's right. Lost March appears to have modelled it on the ACO membership.
Membership gives: earlier ticket access, dedicated grandstands, discounted tickets, forward parking, access to paddocks at the Revival meeting and access to members enclosure.
Which, now I've written it down, does not seem like a good deal.
There is said to be a large waiting list for membership.
My wife worked out that there are about 7 levels of privilege at Goodwood and Le Mans:
Drivers
Teams
invited guests and celebrities,
corporate sponsors,
corporate hospitality guests
ACO/Goodwood Members
Public
