FactThe GSX's 455 V8 made 510 lb-ft of torque — more than any American performance car until the Dodge Viper finally beat it, 33 years later.
The GSX / GSX Stage 1 was Buick's contribution to the classic-era muscle-car list, based on the GS 455 and adding an appearance, performance and handling package (a US$1,100 option on top of the US$3,098 Gran Sport) starting in the 1970 model year; it was Buick's answer to Pontiac's GTO Judge, Oldsmobile's 4-4-2 W-30 and Chevrolet's Chevelle SS, advertised as "A Brand New Brand Of Buick". A prototype with Mother of Pearl white paint was shown at the Chicago Motor Show in February 1970 and only 678 GSXs were produced in the second half of the 1970 model year (278 with the standard 455 and 400 with the Stage 1), in Saturn Yellow (187) or Apollo White (491), always with the 455 cu in engine and black interior; power output was rated between 350 and 360 hp, and its 510 lb-ft was the highest torque output of any American production performance car until the 2003 Dodge Viper. Standard equipment included a black full-length stripe over a rear spoiler, hood-mounted tachometer, black bucket seats, floor shifter, wide oval tires, quick-ratio steering, front and rear anti-sway bars and a quad-link suspension with a limited-slip differential. During 1971 and 1972 the GSX became an option available on any Gran Sport, with production dropping to 124 and then 44 units (including the 350-4 bbl option, the standard 455 and the Stage 1 engines).

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

Photographs
The 1992 Skylark's wedge shape and pointed grille weren't new — Buick previewed them on the 1990 Bolero concept, and that grille itself was a callback to 1930s Buick Specials.
The N-body coupe was badged "Somerset" at launch — Buick had already used that name once before, as a trim package on the Regal.
1985 was the end of the line for the X-body Skylark's two-door coupe — Buick dropped it for a sedan-only lineup as the body style moved to the new Somerset Regal.
This Skylark broke a 62-year streak — the first four-cylinder Buick since the original Buick Four was dropped back in 1918.
Buick had to buy back its own V6 tooling from American Motors, which got it via the Kaiser Jeep deal, to build the 1975 Skylark.
The GSX's 455 V8 made 510 lb-ft of torque — more than any American performance car until the Dodge Viper finally beat it, 33 years later.
At 510 lb-ft, this GS 455's big-block held the American muscle-car torque record for over three decades — until a 2003 Dodge Viper took the crown.
Buick sold its discontinued V6 tooling to Kaiser Industries, where it went on to power Jeep trucks instead of Skylarks.
The GS 350 was the baby of Buick's muscle-car GS line, but it outlasted the bigger GS 400 and GS 455 — running until V8 Gran Sport production ended entirely in 1975.
The GS California wasn't a nationwide car — in its 1967 debut year, Buick sold it in California only and never advertised it anywhere else.
Buick split its 1967 Gran Sport in two: the big-block GS 400 came in multiple body styles, but the cheaper 340-cubic-inch GS 340 was sold only as a two-door hardtop — no other way to get one.
The '400' in GS 400 undersold it — the real engine was a 401 cubic inch V8, trimmed to fit GM's internal cap on how big an intermediate's engine could sound.
Buick's Gran Sport ran a 401-cubic-inch V8 — but sales brochures listed it as 400 cubic inches, dodging a GM corporate rule that capped intermediate cars at exactly that limit.
Buick sold off the tooling for its aluminum 215 V8 after dropping it here, and Rover kept building that engine until 2006.
The 198 V6 that debuted here was the first American V6 built in volume production, cast in iron off the aluminum 215 V8's design.
Buick sold only 836 of these Skylarks in 1954, undercut by buyers who saw it as a step down from the Roadmaster it borrowed from.
The 1953 Skylark cost over a thousand dollars more than the Roadmaster convertible it was built from, for a car sharing most of the same tub.
Rivals
Same body, same money, other badges — tap any card to flip.
It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.
Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.
A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.
The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.
The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.
The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.
The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.
This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
