Welcome, Graham!
Some great advice above!
As Stephen said, it’s not a formal Club service, but it IS something many of us have done to help fellow members out. There’s no hard and fast rules, and the typical currency for compensation is beer! (That said, the last time I helped someone like that, it was a hundred plus miles either direction, so the guy did offer to pay the fuel bill, which is fair enough).
Depending whether you’ve been able to try sitting in/driving any Westfields before, will decide how essential it is to be there when looking over and testing one yourself. Unlike the classic car market for the Jaguar example, where, an XJS HE from 1982 for example, should be a fairly known thing in terms of spec, and all that’s really needed is to check it is what it’s claimed to be and it’s condition. With kit cars like Westfields, you have to allow for almost no two cars being totally alike, even if they’re factory builds of the same “model”. This variation only gets wider the older a car gets; we all like to personalise them to make them our own, and often to adapt them to better give us what we personally enjoy from the car, and for how we each use them.
But then this is the fantastic part of kit cars like Westfields; they grow and adapt to suit their owners preferences and needs, and what they find fun!
The more exposure you have to the cars, through Area Meets and events, the more you will know what you want to look for in a car of your own; it’s always cheaper to get one close to your preferred spec, than to modify one to get there.
Best of luck with the search, the car of your dreams will be out there, with a little patience!
