Edited sentence: After Roosevelt’s death, the limo remained in the fleet and was occasionally used by President Truman until 1948, and is now on permanent display at the Henry Ford Museum in Dearborn, Michigan.However, after the Japanese attack on Pearl Harbor, the Secret Service began to express concern in relation to potential assassination attempts against the president.Roosevelt used the Capone car until his "Sunshine Special" was modified to be bullet-proof, with armor plating for the doors, bullet-proof tires, inch-thick windows and storage compartments for sub-machine guns.The Ford Motor Company leased the car to the Office of the President for $500 a year.The car had been confiscated by the Treasury Department following Capone's arrest and stored in an impound lot until its ironic final duty.The following day, 8 December 1941, a heavily armored 1928 Cadillac 341A Town Sedan, that had originally belonged to gangster Al Capone, was used to transport the president to the Capitol to deliver his "Infamy" speech.The limousine was originally equipped with a siren, running lights, a 2-way radio, extra-wide running boards, and grab handles for Secret Service agents, and had a convertible roof as a way for President Roosevelt to communicate with the crowd, without actually leaving the vehicle
