I think they can do the paperwork pretty quickly. And I'm reasonably sure they let you do test drives.

Just need to make sure that the driving customer has the beer after their test drive. You can fill up the companions before, however.

But to strengthen your point: I don't know for sure, but from what I can tell by looking at the place there's barely enough inventory at that showroom to allow some test drives. It's definitely not a car lot.
