Carried over with only modest trim changes, Sevilles got a retuned suspension to improve their ride, plus new body mounts.
Nameplates moved from the upper right of the grille to the upper left, and that grille had a tighter pattern than before.
The grille’s pattern of vertical crosshatch slots was repeated in twin insets in the front bumper.
Standard engine remained the 350 cu. in. (5.7-liter) V-8 with electronic fuel injection, now rated 170 horsepower.
The diesel version introduced at mid-year was offered again.
Sevilles destined for California received the three-way catalytic converter with closed-loop electronic controls, previously used only on other GM models.
Bodies could have 14 standard colors, with seven Firemist colors available.
Interiors came with new solid and striped Dante and Roma knit fabrics in six colors, or 11 shades of Sierra Grain leather.
Either the Tuxedo Grain padded vinyl roof (in 17 colors, including metallics) or a plain metal top were offered at the same price.
Options included the new digital trip computer and signal-seeking radios.
Cadillac’s catalog claimed that Seville had been chosen “one of the ten most beautifully designed production cars of the last 50 years.” The special edition Elegante came in two-tone Slate Firemist and Sable Black, with accent striping and full-length side moldings with etched black grooving, plus a painted metal roof.
Elegante was identified by a Cadillac wreath and crest as well as script nameplate.
