But they called themselves "American Bus Industries" -- you can always trust a label like that, right?
No, they're NORTH American Bus Industries (NABI), which means they could be in Mexico if they wanted! Isn't NABI actually in Canada? I think NABI is the successor to the ill-fated collaboration between Crown in Los Angeles and Ikarus from Hungary, whose bendy-buses were not a complete success here. Apparently they were the only Crowns that did not have Crown's usual 20-year warranty that their school buses had.
