SS-100-X

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 one that Kennedy and First Lady Jacqueline Kennedy were passengers in 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.

SS-100-X was originally a standard 1961 Lincoln Continental four door convertible (model 74A) built by the Ford Motor Company and assembled at the Wixom, Michigan plant. It had a retail price of $7,347 (equivalent to $58,277, as of 2015).

The car was moved to the Experimental Garage at the Ford Proving Grounds where an additional 41 inches was added between the front and rear doors and just beyond the rear doors. The car's frame was strengthened to accommodate the additional length and weight. It was painted a special navy blue color and taken to Hess & Eisenhardt of Cincinnati, Ohio for reupholstering and further modifications to Secret Service specifications. During the refit the car had no bulletproof or bullet-resistant additions added. The windshield remained the standard two-ply safety glass which could be easily replaced at any dealership.
