1975 Buick Riviera: Stage One Ends, and the GS Becomes a $73 Option
Stage One dropped; the GS handling package continued on 3,101 of 17,306 cars.
United States · researched through 2026-09-22
The Riviera Owners Association lists 17,306 Rivieras for 1975, this record's own overview states, including 3,101 with the GS handling option, the standard 455 listed at 205 horsepower SAE net. This record's own key facts section adds that 92.8 percent of 1975 Rivieras had power seats, 72.8 percent cruise control, 99.5 percent air conditioning, 49.1 percent an 8-track tape deck and 75 percent a vinyl top, and that the GS package itself cost $73.1,2,3
This record's own identification section, a single entry for 1975, describes the year as the one in which Stage 1 was dropped from the lineup entirely, leaving the GS ride-and-handling option to continue on its own as the sole performance-adjacent package, with gold GS emblems mounted below the Riviera script on the front fenders; the Owners Association's own GS table gives the engine code for the year as AF, and this record's own text does not list a separate Stage One code, since none was offered.4
This record's own options section prices the GS and Handling package under code A9 at $73 for 3,101 cars, bundling JR78-15 steel-belted radial whitewall tires, specific springs and shocks, a heavy-duty front stabilizer bar, a rear stabilizer bar, a specific insulation package, and GS ornamentation, its own installs note crediting the 3,101 figure to the Owners Association's production table for the year. This record's own prices section carries a single figure for the sport coupe, $6,403, effective from a price revision dated March 1, 1975.5,1
This record's own options section itemizes 86 entries in total, most of them priced individually by the Owners Association's own transcription of the 1975 order form. Several rows carry no standard order code as printed, including a $15 trailer-tow flasher and harness for five-wire hookups, a $25 version for seven-wire hookups, a $16 rear stabilizer bar, a $119 special-order paint charge, a $45 two-tone paint and rear-quarter belt-finish molding charge, and separate custom vinyl-roof, Landau-roof and leather-upholstery groups priced at $132, $389 and $302 respectively.5
This record's own paint table carries 15 colours from the Owners Association's 1975 chart, its own note adding that two-tone paint was available and that expanded vinyl roof coverings came in eight colours of their own. Its interiors section carries 29 trims across a standard Lombardy cloth-and-vinyl notchback bench in four colours, optional vinyl 60/40 and 40/40 notchback and bucket choices including several white-combination options, a vinyl-and-Lombardy-cloth 60/40 notchback group, and a leather-and-vinyl 60/40 notchback pairing in Saddle and Black.6
This record's own specifications section carries seven 1975 figures from the Owners Association's weights-and-measures table: a 5,002-pound curb weight, a 122.0-inch wheelbase, front and rear track of 63.6 and 64.0 inches, a 223.0-inch overall length, an 80.0-inch width, a 54.0-inch height, and a JR78x15 tire size. This record's own conflicts section notes a discrepancy between the Owners Association's own production table, which gives 17,306 Rivieras for the year, and its own Evolution article text, which gives 17,036; the table figure is kept, since the Evolution number looks like a transposition, and this record's own unpublished-leads section is empty for the year.7,3

- Dodge Dart GTS, Swinger and Demon The Dart 360 Sport continued into 1975 at $4,014, but Flory prints its production as not available.
- Ford Maverick Grabber The Grabber's last year: 8,473 by Classic Industries count, about 8,500 per Consumer Guide.
- Ford Ranchero GT The Ranchero GT continued on the 1972-76 Ranchero; 6,114 GTs were built, per reference-site counts in the Standard Catalog lineage.
- Ford Thunderbird Sixth-generation personal-luxury Thunderbird; the record holds the production total and the luxury-group option prices only.

- Mercury Cougar Outside the muscle focus: 62,987 Cougars for 1975 per Wikipedia's table.
- Oldsmobile Cutlass, 4-4-2 and Hurst/Olds The Hurst/Olds introduced Hurst Hatches T-tops on the Cutlass Supreme coupe; 2,535 were built, 1,293 white and 1,242 black.

- Plymouth Road Runner The Road Runner moved to the Fury host for one year.
- Pontiac Firebird and Trans Am The year the Trans Am took over the line: 27,274 built, more than twice the Formula.
- Pontiac Grand Am The last of the Colonnade Grand Ams: catalytic converter, a $4,887 start, and 10,679 built.
- Pontiac Grand Prix The LJ joins the line; the 455 is down to 200 hp net.
- Pontiac Tempest and LeMans Catalytic converters, standard radial tires and Radial Tuned Suspension arrive, the 455 leaves the LeMans, and the GT option becomes an automatic-only V8 package.
