It had been created by the talented Italian design studio, Pininfarina, to showcase their ideas to Cadillac. Their contract with Cadillac was coming to an end as the limited production bodies for the Eldorado Broughams were no longer created after 1960. Their strategy was to convince General Motors management that an updated and stylish limited production would continue the legacy of the Eldorado Brougham. Pininfarina developed a pair of unique custom cars, both two and four-door versions of what they hoped would become the replacement for the Eldorado Brougham. The name 'Jacqueline' was chosen in honor of the newly elected President John F. Kennedy's wife. Pininfarina hoped that their concept would have similar qualities as the First Lady, and so the concept was dubbed 'Jacqueline.'
The car shown at the Paris Auto Show was well received by members of the press. It had advanced styling with chrome accents that were supportive of the vehicles design but not overstated. The grille was clean and the rear featured wrap-around taillights. There were thin pillars allowing for ample views of the countryside. The front end was signature Pininfarina styling, with dual headlights on each side. In keeping with the heritage of the Pinin Farina built Brougham, a few design elements were retained such as the A-pillar along with the basic windshield design, the steering wheel, the basic dashboard layout, and the Cadillac wheel covers.
It was originally finished in Cadillac's Ermine White and accented with a brushed stainless steel to, similar to the 1957 and 1958 Brougham. The interior was black with modest amount of chrome; there were one-piece bucket seats with a center armrest and a special compartment behind the passengers to store luggage, picnic basket, or possibly a set of golf clubs.
Though the Jacqueline Concept was never put into production, Cadillac and the General Motors Division did incorporate some of its design aspects into their model lines.
Once the days of the show circuit had come to an end of the Jacqueline, the car was put into the Pinin Farina museum. It would stay there for more than 30 years and only shown on vary rare occasions. During the mid-nineties, Pininfarina sold their design study from the 1960s and the Jacqueline eventually ended up in the United States.
