We all know that the US President rides around a big Cadillac nicknamed The Beast. You probably also know that it's not really a Cadillac, but an armored behemoth built on a heavy-duty truck chassis. And should you ever see POTUS on parade, you'll definitely see the convoy that goes along for the journey. It's usually a cavalcade of black Chevrolet Suburbans, with perhaps a SWAT vehicle or two thrown in for good measure.
