There's a VP2 based here at Sheepwash in Devon. It seems in quite reasonable nick. I think there's a chance the owner may be willing to sell, but I don't know.
From what I hear, though, the VP2 is no delight in terms of handling and has very marginal power. It looks as ugly as sin too.
It's G-BXOC and the owner's details are on G-INFO.
