The Cadillac Allante was the first hyper luxury roadster that hit the market in 1987 and was sold successfully till 1993. The Allante was designed to restore the position of Cadillac as a competitor of the Mercedes-Benz 560SL.
The car initially had the code name Callisto and its engine and chassis were obtained from the Cadillac Eldorado. It also shared some of its components with the Buick Reatta, Oldsmobile tornado and Riviera. The chassis of the car was manufactured in Detroit from where it was shipped to Italy on specially equipped jets. 
Once the body of the Cadillac was mounted to the chassis, the cars were shipped back on jetliners to the plant in Michigan for the finishing touches. The process gave the car nicknames like “the world’s longest assembly line” and “The Flying Italian Cadillac”. The price of US$54,000 for the Cadillac was more than the price of any Cadillac of its time.
The car had an independent suspension system with the standard four wheel disc brakes. The car went under many changes over the years with the introduction of the Speed Dependent Damping Control in the 1989 Allante. Apart from the new road sensing system and improved disk brakes, the other significant changes for the Allante included deeper front spoilers, power steering rack and the single piece side windows.
There were as many as 21000 Cadillac built during its time of production. The car made its appearance in some of the hit movies of Hollywood like Tango & Cash, Terminal Velocity and Rocky V. Awarded as the peace car at the 1992 Indianapolis, the car was also driven by Jr. Ewing.
