Not sure if anyone's seen this or not, but I couldn't find it by searching past threads.
There is a show on Amazon called The Man In The High Castle. Aside from it being a very good series, they make heavy use of vintage buses in the various episodes. Not sure exactly what buses they are, since they're disguised a bit, but fascinating nonetheless. If you've got Amazon Prime you can watch it for free.
Here's a blog post about one of the buses.

I was on my way home from work (Seattle public transit) one evening a few years ago and came out of the bus tunnel at Union Station to see a film crew in progress. They had vintage seated coach a few vintage cars and a old motor cycle with sidecar parked at the Union station. I was able to take a few pictures before I was told not to take pictures. I'll post them if I can find them. I later found out it was the set for The Man In The High Castle.
Saw an older shipping wars program today. They hauled a scenicruiser.
Great series
