As far as car events, your absolutely dead on. I've frankly been struggling with this very issue for some time now. The delivery situtaion however shouldn't effect doing karting or just having a social get-together. I think our first event is shaping out to be a Elise intro and club event will be Princton Sport and Specialist Cars in September.
I'm going to throw this out a little early but I've been working on a Lotus Tour for Club111 members for late summer 2005. This would included a factory tour, tour for team lotus, the donnington muesum, and track time with Lotus Driving Instructors on their test track. Any interest?
