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.
In the '60s and '70s muscle cars were all the rage, and it was common for legendary machines to be overshadowed by genius marketing campaigns and muscle legends like the Ford Mustang and the Chevrolet Camaro. Present today is one of those legendary muscle machines that did not receive the spotlight it deserved, and it takes shape with this iconic 1971 Buick Gran Sport Convertible.

1970 marked an important year for Buick’s midsize muscle car lineup, as the Skylark 350 Sport Coupe blended the brand’s signature comfort with increasingly aggressive performance styling. While Buick’s GS models often stole the spotlight, well-optioned Skylarks like this example have become increasingly appreciated for offering the same muscular A-body proportions and V8-powered driving experience at a more approachable level. Showing approximately 19,245 miles on the odometer, this Skylark benefits from a substantial refurbishment and modernization effort that included drivetrain work, suspension upgrades, steering enhancements, interior refresh, and cosmetic refinishing. Finished in Bamboo Cream over a Saddle vinyl interior, this Buick stands out with tasteful GS Stage 1-inspired styling cues, upgraded handling components, and classic American muscle car presence.
The first-generation Buick Riviera remains one of the most elegant American personal luxury coupes ever produced, and the 1967 model represents the final and most refined year of the original design. Penned under the direction of Bill Mitchell, the Riviera combined dramatic proportions, hidden headlights, and unmistakable GM styling with serious big-block performance, creating a uniquely sophisticated grand touring machine. This 1967 Buick Riviera, showing just 3,059 miles, presents as a beautifully restored and tastefully upgraded example finished in striking Blue over a Blue and White interior. Powered by Buick’s formidable 430ci V8 and enhanced with select performance and cosmetic upgrades, this Riviera offers the ideal blend of classic luxury, vintage American muscle, and effortless cruising presence.
The 1963 Chevrolet Corvette Convertible represents one of the most significant years in Corvette history, introducing the revolutionary second-generation C2 platform that would become known as the Sting Ray. While the split-window coupe often receives much of the attention, the convertible delivered the same groundbreaking styling and performance in an open-air package that perfectly captured the spirit of American sports car motoring. This particular example shows approximately 426 miles and is presented in the timeless combination of Ermine White over a red vinyl interior with a matching white soft top. Equipped with a 327ci V8, desirable 4-speed manual transmission, and classic turbine-style wheel covers, this Corvette offers collectors and enthusiasts an opportunity to own one of Chevrolet’s most iconic designs in a highly attractive factory-style specification.
Cadillac entered the 1980s as America’s premier luxury marque, and the DeVille remained one of its most recognizable flagships. Designed to deliver effortless cruising comfort, elegant styling, and a commanding road presence, the DeVille embodied the traditional American luxury car formula that Cadillac had perfected over decades. This 1980 Cadillac DeVille shows 90,728 miles and is finished in sophisticated Western Saddle Firemist Metallic with a matching Saddle Velour interior. Equipped with the desirable d’Elegance Package, a black vinyl roof, and modern upgrades including 22-inch aftermarket wheels and a Kenwood audio head unit, this DeVille successfully blends classic Cadillac luxury with a customized appearance that is sure to stand out wherever it goes.
The 1972 Porsche 911 T Coupe represents one of the most unique and collectible variants of the long-hood 911 lineage. As part of Porsche’s F-Series generation, the 911 T combined lightweight driving dynamics with the company’s proven air-cooled flat-six formula. The 1972 model year is especially significant because it was the only year Porsche fitted the now-famous external oil filler door, known by enthusiasts as the “Ölklappe.” Designed to improve weight distribution by relocating the oil tank ahead of the rear axle, this feature has become one of the most recognizable identifiers of a genuine 1972 911. This example is finished in attractive Albert Blue over a tan interior and shows approximately 76,346 miles.
