That ribbed aluminium siding, small square windows, extruding signage, it all looks very 50's to me.

Do modern US coaches really still look like that?
They must have huge expanses of curved glass by now!

On my last trip to New York I noticed lots of archaic trucks and vans, when I looked closer I found out they were brand new.
Deliberately styled that way?

It was a weird mix of old and new. Like the way our airport/hotel minibus had 1950s styling but also had free WiFi!
