It rolled off the line at the Fleetwood assembly plant in 1955 as an eight-passenger Imperial sedan, and was subsequently modified for state duty. In addition to the power brakes, tinted glass, rear compartment radio, heating and air conditioning that it came with from the factory, Hess & Eisenhardt of Rossmoyne, Ohio, fitted it with the rear roof section from the Series 62 Coupe de Ville and a sunroof with grab rail for parade duty. The White House held onto it until long after the Eisenhowers left office, replacing it with the ill-fated Lincoln Continental that fatally served the Kennedy administration.
