Atlantic, cut apart, lengthened by and reworked. Later models were built from four-door models to the same specification. Each took a month to build and carried a high price for the time of US$18,500 in 1963-64 ($ in dollars ). They sold in limited numbers against the Cadillac Series 75 that was less expensive at US$9724–$9960 in 1963-64 ($ in dollars ), and had an established reputation among limousine buyers, as well as against competing coachbuilders building on the Cadillac commercial chassis. Packard had ended production in 1957 and both the Mercedes-Benz 300d and the Rolls-Royce Silver Cloud had just been introduced. A total of 132 Imperial Crowns were manufactured for Chrysler by Ghia over 1957-65. An oddity is that these cars were often built as soon as the styling changed, and sold over a period of some years. All 1961 Imperial Crown Ghias used the 1960 styling front and rear, for example, and all 10 Ghia built Imperial Crowns sold during the 1965 model year were 1964s with 1965 exterior styling and consequently had a TorqueFlight pushbutton gear selector. At about curb weight the 1957-65 Ghia built Imperial Crowns are the heaviest standard production cars sold by an American firm since the 1930s. Throughout her husband's term as U.S. President, Jacqueline Kennedy's personal car was a Ghia built 1961 Imperial Crown with 1960 model year styling. The car figured prominently in her various duties as First Lady. In President John F. Kennedy's funeral procession on November 25, 1963, near the front of the motorcade, carrying Jackie and her children, was her Imperial Crown. New York governor and heir to the Standard Oil fortune Nelson Rockefeller, later Vice President of the U.S. during the term of President Gerald Ford, also owned a 1960 Imperial Crown. It is one of 17 limousines made by Ghia in that year, and the only one with blind rear quarter treatment. In the 1974 movie The Godfather Part II, a black Ghia built 1958 Imperial Crown was used by Michael Corleone (played by Al Pacino) while at the family compound near Reno, Nevada. Imperial Crown (1967–1971) and Imperial (through 1983) While the "Imperial Crown" limousines ended in 1965, Imperial limousines continued to be made by other coachbuilders. After the last ten Ghia-built Imperial Crowns were completed, Ghia sold its tooling to Barreiros Coachbuilders of Spain. Barreiros built ten limousines, much like those built by Ghia
