sounds like you are describing a mexican bus, the busses that are
currrently FS in mexico sound like very much what you describe, it looks
like a bay window era bus except that the roof has been somewhat squared
off (looking kinda like a "bricks" pop up roof), has a black radiator
mounted on the front as well it has very vanagon-esque mirrors and impact
absorbing (is this the correct term) "safety" bumpers.

it is my understnading that these busses couldn't mean US DOT safety standards
