@pip-bip -- Wow, I've never seen one of those, only the Checker equivalent, the Aerobus. Turns out, though, that there's a long tradition of making things like this out of both Chevy cars and (somewhat more sensibly) Suburbans.
I gather that a company called Armbruster-Stageway (whose origins date back to when they made actual stagecoaches) usually did the deed. They're still around, but more focused these days on your last ride.
