1990 Buick Riviera: The 14-Way Seat Replaces the 16-Way

This record's own dek gives 22,526 Rivieras for 1990, a figure this record's own production section credits to both the Owners Association's own table and Wikipedia's own production table together, its own note calling the two lineages in agreement. This record's own key facts section, drawn from the Evolution article, states that the Delco/Bose audio system stayed optional for the year and that a 14-way power seat replaced the previous 16-way seat, the same entry pricing leather-and-suede seats at $550, the sunroof at $1,230 and the cellular telephone at $1,975.^1,2,3

This record's own options section confirms the 14-way seat change directly: code AF9 now names a "14-way Driver Seat with Leather & Suede" priced at $325, distinct from the standard cloth AR9 buckets and a separate $550 leather-and-suede AR9 upgrade. This record's own prices section carries a single figure for the sport coupe, $23,040, sourced to both the Owners Association's own options-and-prices transcription and its Evolution article together, with no separate figure given for either source alone.^4,3

This record's own options section itemizes 18 entries in total, priced individually by the Owners Association's own transcription of the 1990 order form, including a $695 heavily padded vinyl Landau top under code C84 offered in eight colours, a $1,399 Delco/Bose compact-disc and cassette radio under code UIG, a $516 graphic-equalizer compact-disc radio under code UIH, and a $104 Gran Touring Package under code Y56 bundling a Gran Touring suspension, a 2.97 axle ratio, a leather-wrapped sport steering wheel and shift handle, fast-ratio power steering, and Eagle GT+4 tires.⁴

This record's own options section also prices a Riviera Appearance Package under code RIV at $205, bundling Platinum Beige Firemist lower accent paint, a body-side stripe and painted aluminum wheels, and requiring specific paint and trim codes to order; and a Lower Accent Paint option under code D84 at $190 that this record's own text says requires one of seven specific body colours, alongside a body-side stripe choice this record's own text lists in ten separate colours.⁴

This record's own paint table carries 12 colours from the Owners Association's 1990 chart, its own note listing twelve Landau vinyl-top colour codes, every entry sourced to the same color-and-trim page as the interiors below it. Its interiors section carries 15 trims across standard cloth buckets, extra-cost leather-and-suede buckets, and the 14-way driver's bucket described here as leather and vinyl rather than leather and suede, each in colourways drawn from Blue, Brown, Slate, Taupe and Red.⁵

This record's own specifications section carries seven 1990 figures from the Owners Association's weights-and-measures table: a 3,497-pound curb weight, a 108.0-inch wheelbase, front and rear track of 59.9 and 59.9 inches, a 198.3-inch overall length, a 71.6-inch width, a 53.5-inch height, and a dual P205/70R15 standard and P215/65R15 optional tire size. This record's own identification, conflicts and unpublished-leads sections are all empty for the year, and its own engines, performance and transmissions sections carry no entries either, leaving the key facts and options sections as this record's own richest sources for 1990.⁶
