A 1972 Buick Skylark Gran Sport wearing GSX badges has just surfaced for sale through GAA Classic Car Auctions, currently listed in Motorious inventory. Finished in bronze over a black interior, the coupe pairs a 455 cubic-inch V8 with a hood-mounted tachometer, bucket seats, and a center console, the kind of hardware that separates a genuine performance car from a dressed-up grocery getter.
Buick's Gran Sport line traces back to 1965, when the division decided its A-body coupes needed more muscle to compete with the GTOs and Chevelles dominating the era. The GSX package arrived in 1970 as the halo of the lineup, wrapping the 455 Stage 1 engine in bold graphics and a rear spoiler. Production of true GSX cars was always tiny, and by 1972 tightening emissions rules and insurance surcharges had thinned the ranks even further, making any surviving example with the badge worth a closer look at its build sheet and paperwork.
This particular car backs up its GSX badging with a Turbo-Hydramatic 400 transmission, 3.42 rear gears, and an aftermarket aluminum intake feeding the big-block. Factory air conditioning suggests it was built for comfortable cruising as much as stoplight duels, and the seller notes the paint is only a year old, so the presentation is fresher than the typical 50-year-old survivor.
For buyers trying to gauge what a car like this should cost, Hagerty Valuation Tools is a good place to start. Hagerty's price guide puts a #3 (Good) condition 1972 Skylark 350 coupe at roughly $16,500, and GS and GSX variants have historically traded well above that baseline once their performance equipment and documentation are verified. Looking at three years of auction results for the model, Hagerty has tracked sales ranging from under $3,000 for rough project cars up to more than $70,000 for the best-documented Gran Sport and GSX examples, a spread that shows how much drivetrain authenticity and condition swing the numbers on these A-bodies.
Shoppers weighing this Skylark against other early-1970s muscle should also see how Chevrolet's competing platform is trading; Motorious recently rounded up the 10 Coolest Chevy Chevelles for Sale Right Now for exactly that kind of comparison. Buick's own Skylark lineage is worth a deeper look too, and our research piece on the 1971 Buick Skylark covers how the model changed just one year before this GSX-badged car rolled off the line.
The Skylark is part of GAA Classic Car Auctions' in-progress inventory out of Greensboro, North Carolina, and remains available to view through Motorious. For anyone hunting a big-block Buick with the right badges and the paperwork to back them up, it is worth a call before the gavel drops.
