The 20th anniversary version of the Eldorado featured changes in its suspension and engine damping. The use of deflected disc strut valves on cars with the touring suspension provided a more comfortable ride and better road manners. New hydro-elastic engine mounts were also used. New vehicle-sensitive rear seat belts were used on all Eldorados. A new cashmere cloth and leather interior trim was offered. Twelve new exterior colors, for a total of 19, were introduced. Larger P205/75R14 standard tires was also used. For the first time, Cadillac offered the cabriolet top as an option for the base Eldorado. The Biarritz had a redesigned cabriolet top.
