I don't know exactly what's so cool about this old bus, but I can't get over how sweet it looks.
It's a '35-'36 Kenworth bus. It wasn't the first double-decker (technically you should call this a bi-level), but it was way ahead of the curve. The now-legendary GM Scenicruiser didn't debut until a quarter-century after this Kenworth, as Curbside Classics states.
