The limousine, in which US President John F. Kennedy was riding on the day of his assassination, went on to serve three other presidents.
The tragic car, which is now at the end of the road in the Henry Ford Museum in Dearborn, Michigan, was used until 1977, years after the assassination, by presidents Richard Nixon, Gerald Ford and Lyndon Johnson, CBS News reported.
Museum's curator Matt Anderson told the publication that when Kennedy had the car, it was not armoured in any way, shape or form and the tires were not bulletproof.
He said that there was no bulletproof glass, it did have a removable plastic top, and was just Plexiglas.
Anderson said that after the accident, the car was rebuilt as a true armored vehicle and the biggest change they made in modifying the car was putting in a permanent roof that could not be removed, while surrounding the whole vehicle with bullet-resistant glass.
