The Buick GS 455 remains one of the most respected muscle cars of the golden era, pairing Buick’s reputation for comfort and refinement with the brute force of a massive big-block V8. While many enthusiasts gravitate toward Chevrolet, Ford, and Mopar offerings, the GS 455 has earned a loyal following thanks to its impressive torque output and understated styling. This 1970 Buick GS 455 Coupe shows approximately 94,245 miles and is finished in its iconic Gulfstream Blue color combination. Featuring desirable GS styling cues, performance-oriented upgrades, and a well-appointed interior, this Buick represents a compelling opportunity to own one of the most capable and collectible muscle cars of the early 1970s.
Exterior and Interior
The exterior of this 1970 Buick GS 455 Coupe is finished in Gulfstream Blue and showcases the muscular styling that helped establish the GS as Buick’s premier performance model. The car features a custom paint job completed in its factory-correct Gulfstream Blue color, providing a striking appearance that highlights the GS’s sculpted body lines. Signature features include the GS hood scoop, proper GS decals, original-style bumpers, trim, and emblems, along with 15-inch factory chrome wheels wrapped in performance raised white-letter tires. The car’s aggressive stance is further complemented by aftermarket rear air shocks, while the detailed engine bay and underbody reflect the level of care invested in the vehicle. From every angle, this GS 455 delivers the classic muscle car presence enthusiasts seek. The interior of this 1970 Buick GS 455 Coupe features blue upholstery and a host of custom interior enhancements designed to maintain the car’s classic appearance while improving comfort and usability. Highlights include custom seating surfaces, door panels, headliner, parcel shelf, carpeting, and weather seals. A Bluetooth-compatible stereo system and rear deck speakers provide modern audio functionality, while a digital tachometer and additional instrumentation contribute to the car’s performance-oriented atmosphere. The result is a cabin that blends vintage Buick styling with thoughtful upgrades for enjoyable cruising.
Engine
Under the hood sits a 455ci naturally aspirated V8 equipped with an Edelbrock aluminum intake manifold, Edelbrock 4-barrel carburetor, Comp camshaft, headers, and a custom dual exhaust system. A Mallory electronic ignition system enhances ignition performance, while an upgraded 4-core radiator and transmission cooler lines assist with temperature management. Power is routed to the rear wheels through a 3-speed automatic transmission, delivering the effortless acceleration and abundant torque that made the GS 455 famous. Additional features include power-assisted front disc brakes, an aftermarket master cylinder, aftermarket fuel tank, and aftermarket rear air shocks. Combining legendary Buick big-block performance with carefully selected aftermarket upgrades, this GS 455 offers a rewarding driving experience that remains true to its muscle car roots.
The 1972 Buick Gran Sport is a great example of why Buick’s muscle cars have always had their own following. Where some competitors leaned almost entirely into aggression, the GS mixed real V8 performance with a more polished, upscale feel, and this 60,979-mile example captures that balance nicely. Finished in Burnished Copper with a Black vinyl roof over a Black interior, it pairs a 350ci V8 and 4-barrel carburetor with a TH350 3-speed automatic and rear-wheel drive. The equipment list is especially appealing for an enthusiast cruiser, with power disc brakes, power steering, air conditioning, a full-length console, Rallye steering wheel, tinted glass, chrome-plated wheels, and period stereo equipment all part of the package. It has the visual presence of a proper early-1970s muscle car, but with the comfort and restraint that made Buick’s Gran Sport line feel a little more grown-up than the average stoplight bruiser.

Buick’s Gran Sport or GS badge was applied to several of the brand’s high-performance variants of models such as the Skylark, Riviera, Wildcat, Century, Apollo, and more. Since Buick was meant to be a luxury brand slotting in just beneath Cadillac in GM’s hierarchy, the Gran Sport badge represented the sportiest luxury car from GM, since Cadillac did not do sporting machines. Up for sale today is a fully restored 1969 Buick Gran Sport 350 with a total 77,364 miles on the clock and only 500 miles reported since its comprehensive makeover. The car also comes with some interesting updates, making it easier and more pleasurable to drive.

The 1984 Buick Riviera Coupe comes from an era when personal luxury cars were all about presence, comfort, and a sense of occasion, and this example delivers that character in a particularly period-correct package. Showing 41,329 miles, it is finished in Light Sand Gray over a Burgundy velour interior and powered by a 307ci V8 paired with a 4-speed automatic transmission and front-wheel drive. The padded Burgundy vinyl roof, burl woodgrain trim, split front bench seat, column-mounted shifter, and Riviera hood ornament give it the unmistakable look and feel of an upscale 1980s Buick, while air conditioning, power accessories, and the Concert Sound audio system add the comfort expected from the nameplate. It is the kind of Riviera that appeals less through outright performance and more through its relaxed cruising character, distinctive styling, and richly finished cabin.
The 1961 Buick Electra 225 Riviera 4-Door Hardtop captures Buick at the height of its early-1960s luxury era, combining dramatic styling with a long list of power conveniences. Showing approximately 72,246 miles, this example is finished in silver metallic over a gray cloth and vinyl interior and is powered by Buick’s 401ci Wildcat V8 paired with a Turbine Drive two-speed automatic. Power steering, power brakes, power windows, factory air conditioning and heat, and a Wonderbar radio give it the kind of equipment expected from Buick’s flagship lineup, while the Riviera designation adds further distinction to an already imposing full-size hardtop.

The 1976 Chevrolet Nova Concours Coupe represents the more refined side of Chevrolet’s compact lineup, and this example stands out even further thanks to its rare Concours package and remarkably low 20,299 miles. Finished in Antique White over a Dark Firethorn interior, it pairs a 350ci V8 with a TH350 3-speed automatic transmission and rear-wheel drive. The Concours treatment brought a much more upscale character to the Nova, with a Dark Firethorn vinyl roof, woodgrain interior trim, additional brightwork, and a comfort-focused cabin that separated it from more basic examples. The seller also reports that the interior still smells like new, a detail that speaks to just how unusually preserved the cabin feels. With its low mileage, rare Concours specification, V8 power, and distinctively 1970s luxury-oriented presentation, this Nova offers a particularly interesting blend of originality, comfort, and classic Chevrolet character.
