10. The Presidential Beast 2.0

With an estimated cost of $15.8 million per, the most startling addition on our list is the most recent model of the U.S. Presidential state automobile. Designed on a special General Motors heavy-duty truck base, this car is the height of armoured vehicle modification. The 8-inch thick doors are weight-wise equivalent to those of a Boeing 757 aircraft. Comprising steel, aluminium, titanium, and ceramic elements, the armour can resist direct blows from RPGs and IEDs. During a national crisis, the sealed cabin can act as a mobile command centre and has its own oxygen source. The president's blood type is carried in the vehicle, which also boasts a night vision system enabling it to travel without lighting. Its communication package, which consists of military-grade encrypted equipment and direct links to the Pentagon and Vice President's vehicle, is maybe most remarkable.
