I´ve also splashed out and joined a club here in Holland. (The V44 club was recommended - this caused a bit of confusion as it has now got a new name)

Compared with some clubs in the UK the initial cost is quite high. There are some pretty good advantages though - one for me was their spares webshop which seems to sell new parts at a reasonable price - and importantly later on they will help with a valuation of your vehicle for insurance purposes for a very reasonable price...
...so joined up (again)
