Jim, knowing what we know now we would not:
a) Go to an exhibition.
b) Go on an inspection trip! 😯
Therefore, I doubt they were knowledgeable.
We thought we were “clued up”. Our mistake was trusting the people we dealt with. Why would a lawyer tell lies ❓ I would expect it from an EA to “colour the picture” NOT a lawyer. I think most Brits would be the same.
Mind you, I know of one couple who went on two inspection trips just to get a cheap 4 day break. They were the clients from hell!! They eventually bought a Marriott time share apartment in Marbella that they cannot sell!! 🙂
