As i have said before there is lots of issues with setting up a club like this and i am sure you have thought of most of them already.
It also depends whether you want this club to be criuse and motorsport based as well.
You will need a constitution written, some type of insurance for the club when on cruises, you will need to register as a not for profit organistion, open a bank account in the club name, possibly get a PO box, sort somewhere you can hold regular meeting that can hold all the members you expect that might join and lots of other stuff.
I was the secretary for Nissan SVD quite a few years ago and applaud the guys for trying to get this off the ground as it is not going to be easy and will take alot of there personal time to get up and running and then the people on the committee have to put in a fair amount of time to keep the club running smoothly.
Good luck guys and i will become a member once the club is up, but am trying to organise a wedding with my Fiance so that takes up a fair bit of my time.
