SS-100-X was the U.S. Secret Service code name for the presidential limousine originally used by the 35th President of the United States, John F. Kennedy. The limousine is the car in which Kennedy and First Lady Jacqueline Kennedy were passengers when the President was assassinated in Dallas, Texas on November 22, 1963. Following Kennedy’s assassination, the car received significant armor plating and a bullet-proof hardtop and its navy blue exterior was painted black. It resumed its role as a presidential limousine for President Lyndon B. Johnson until 1967 and later remained in service until 1978, when it was sent to the Henry Ford Museum in Dearborn, Michigan.
