The Fleetwood models had all equipment offered in DeVilles plus Automatic Level Control. The Brougham also came standard with adjustable reading lights; Dual Comfort front seat with Two-Way power adjustment (left side) and a padded vinyl top. Distinguishing Sixty-Specials externally were bright metal wheel house moldings; wide full-length rocker panels with rear extensions and block lettering, denoting the series, positioned in back of the front wheel opening. At the end of the 1970 model run, the "standard" Sixty-Special sedan was dropped. A noticeable trim change was the use of a thin, horizontal belt line molding on all 1970 Sixty-Specials.

Special equipment found on the big Cadillac sedan and limousine included Automatic Level Control; rear window defogger; four rear ash trays; and a manual righthand outside rear view mirror. Separate Climate Control systems were provided for front and rear compartments. Fleetwood wreath crests appeared at the extreme edge of the rear fenders, above the belt molding, on both models. As usual, the doors on the limousine were cut into the roof and a fixed driver's partition with adjustable glass compartment divider was inside. The front compartment was trimmed in genuine leather, the rear in one of five combinations. Three of these were the more standard Divan cloth trims, while Decordo cloth or Dumbarton cloth with leather were the richest selections available
