That is a great bus and a great story.
Only just found the thread, so it made me feel better as we are in the process of bringing a Westy over form the US and we opted to use Kingstown Shipping too.
In my opinion, bringing one over from the States is still viable if it is in the right condition and it is for your personal use. We got an original paint, original interior, low mileage Westy with full history and documentation for a fair bit less that you would pay here, even allowing for the additional costs.
Having said that, if you are looking to renovate and sell then I guess the figures won't stack up.
Hope the bus proves to be as good as it looks and congratulations on a great find.
