Unveiling 'The Beast': Top Secrets of the Presidential Limousine

The development and maintenance of these vehicles are highly secretive. While the cost of a single vehicle is estimated at $1.5 million, the research and development can run into the tens of millions. The limousines are replaced every four to five years to keep up with the latest technological and security advancements. When a "Beast" is retired, it is physically destroyed to prevent its sensitive technology from falling into the wrong hands.
