I think that the problem is that the Greyhound bus is 1/50, which is what we need, but most of our cars and trucks are 1/43. That makes the bus look too small. As an example, I love the New Ray semi's, but they are 1/43 and way too large compared to everything else.

I'm going ahead with using the Corgi and MTH buses I have. For one thing I have about a dozen of them already. I have used the Corgi as the bodies for my 'Streets city buses and intend to power the Greyhound in the phot above.
But I'm convinced they are not exactly 1/50, at least not most, and not even all of the same scale exactly. Buses in the 1950s (like now) varied in the length the manufacturer would make but most of them were right around 96 inches wide (GM-3751, 4103 models, etc.). The Corgi and MTH GM buses are right at 1 and 25/32 to 1 and 13/16 wide which makes them about 1/53 to 1/54 scale if 96 inches width. They are closer to scale in height, the Greyhound bus in the photo above is right at 1/50 in height but about 1:54 in width. Anyway, they look okay when not around 1:43 stuff so I can get by with them.
