Guys - think you might be missing the point with that one. With West Way you can move cars from the group around. The sale goes to the one that acutally sells it. I did this with my original 350z, Basingstoke didnt have one, but another in the group did, so they moved it to Basingstoke where I bought it. I think thats what the OP was trying to get at, it just so happens that they also had another one at his local dealer, although it was too expensive. To try and save some hassle the OP said he'd drive the one they had, but I think they thought he was just after a joy ride.
Either way, go find another dealer and get a proper test drive
