As GM's largest, the "new" D platform designated in 1985 was reserved to Cadillac through the end of its production in 1996.

During most of the 20th century the D-Body represented GM's largest and most exclusive car platform.

Two years later the C platform Series 75 was discontinued, bringing to a close the Cadillac limousine era.

Since all Fleetwood Broughams were being produced in Detroit prior to the name change, initially all late designation D-bodies (1985–1996) were built there as well.

Production ended in 1996, leaving GM without a rear wheel drive luxury sedan.
