The secret service calls it the beast. This limousine went into service when Clinton was president. If you have ever seen the doors open on it they are like bank vaults with huge thick windows. The car is so heavy it over strains the engine and breaks down on a regular basis. It overheated between Tel Aviv and Jerusalem carrying president Clinton. It broke down in Italy with President Bush.
This is some funny footage of it getting high centered. When the car breaks down the president has to get out of the car and expose himself in the open and that kind of defeats having a armored monstrosity. Also, the car is freaking ugly.
