1991 Buick Riviera: A Quiet Year for the 3800

This record's own dek gives 13,168 Rivieras with the 3800 V-6 for 1991, 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 is empty for the year; the options and production sections carry the year's narrative detail instead, the production section again crediting a single agreed total rather than any disputed breakdown.^1,2

This record's own options section prices the seat choices under bare numeric codes rather than letter-number combinations used in most other rows: code 99 for leather-and-suede buckets at $550 over the 19-cloth-bucket standard, and code 98 for a leather-and-suede 14-way adjustable driver's seat at $895. This record's own prices section carries a single figure for the sport coupe, $24,560, sourced to the Owners Association's own options-and-prices transcription alone, with no separate Evolution-article figure given for the year.³

This record's own options section itemizes 18 entries in total, each priced individually by the Owners Association's own transcription of the 1991 order form, including a $1,399 Delco/Bose compact-disc and cassette radio under code U18, a $516 graphic-equalizer compact-disc radio under code U1H, a $104 Gran Touring Package under code Y56 bundling a Gran Touring suspension, a 2.97 axle ratio, 15-inch aluminum wheels, a leather-wrapped sport steering wheel and shift handle, fast-ratio power steering, and Eagle GT-4 tires, and a $205 Riviera Appearance Package under code RIV bundling Platinum Beige Firemist lower accent paint, a body-side stripe and painted aluminum wheels.³

This record's own options section also carries a body-side stripe row that this record's own note says the source gives no price for that year, alongside a $210 pearlescent White Diamond Firemist paint choice under Firemist codes 83U or 95U and a $190 Lower Accent Paint option requiring one of eight specific body colours; a $265 keyless entry system under code AUO and an $80 electric trunk pull-down under code A91 round out the year's convenience options.³

This record's own paint table carries 12 colours from the Owners Association's 1991 chart, its own note listing twelve Landau vinyl-top colour codes, among them Alabaster Beige and Dark Auburn alongside the more familiar White, Black and Silver. Its interiors section carries 15 trims across standard cloth buckets, extra-cost leather-and-suede buckets, and the 14-way driver's bucket in leather and vinyl, each in colourways drawn from Blue, Auburn, Slate, Taupe and Red, every row sourced to the same 1991 color-and-trim chart.⁴

This record's own specifications section carries seven 1991 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 options section as this record's own richest source for 1991.⁵
