The vehicle of POTUS (President of the United States) perhaps is not the most luxurious car you will find, but in terms of safety, it is one of the best in the world. When a US president needs to move around, he does it in style, and he uses all means of transportation.
The presidential vehicles have always been expensive, no matter which president we refer to. Air Force has also contributed for state chiefs to ride comfortably with all the protections included. And safety does matter. So far, Americans have lost four presidents while they were holding the office, but many more actually dodged assassination attempts. One of the most notable presidents was Theodore Roosevelt who got shot during a speech, but he kept going on!
However, the task of transporting the president was taken seriously after 1963 when John Kennedy got assassinated in Dallas, Texas.
