While automotive enthusiasts are well-acquainted with the legendary status of the Buick Grand National—particularly following its recent resurgence in the cultural spotlight—there remains another closely related muscle car from that era that arguably offers an even more compelling driving experience. Better yet, securing one of these rare machines does not require navigating the astronomical market markups typically associated with elite Buick variants like the GNX.
Currently listed for sale at Motorcar Classics is a remarkably preserved 1989 Pontiac Firebird Trans Am, specifically a rare 20th Anniversary Edition. Underneath its hood lies a specialized powerplant derived from the same turbocharged 3.8-liter V6 that propelled its Buick stablemates to infamy. Much like the ultra-exclusive Buick GNX, this anniversary edition Pontiac was produced in a strictly limited run, though in slightly greater numbers to satisfy eager buyers. Pontiac assembled 1,500 units of this commemorative Trans Am, contrasting with the strictly limited production of 547 Buick GNX coupes.
The specific example currently hitting the market presents in remarkably clean condition, a trait that comes as little surprise given its odometer reading of fewer than 30,000 miles. The dealership has listed the car with an asking price of $39,900. For historical context, this specialized performance machine carried an original base manufacturer’s suggested retail price of $30,717 when it rolled off the showroom floor in 1989. When adjusted for inflation, that original figure translates to nearly $70,000 in today’s currency. Viewed through that economic lens, the current asking price represents a notable discount relative to its original purchasing power, provided the vehicle checks out mechanically and structurally without major hidden issues.
Reasonably-priced pace car
During period road tests conducted by automotive publications such as Car and Driver, the 20th Anniversary Trans Am demonstrated blistering straight-line capabilities that shocked the contemporary performance car market. The specialized Pontiac covered the traditional quarter-mile sprint in an impressive 13.4 seconds at a trap speed of 101 mph, while accelerating from zero to 60 mph in a staggering 4.6 seconds. At the time of its release, that performance metric marked the quickest zero-to-60-mph time recorded for any new American production car—surpassing even the flagship Chevrolet Corvette of the era. Prominent commemorative graphics emblazoned across the exterior ensured that onlookers never forgot the vehicle’s other major claim to fame: serving as the official pace car for the Indianapolis 500 in 1989.
Reviewers at the time praised Pontiac engineers for transplanting the high-output, aggressively tuned turbo V6 from the Buick Regal GNX platform into a chassis that offered sharper, more purposeful handling dynamics and aggressive styling. The vehicle was capable of reaching a top speed of 153 mph. While official manufacturer specifications quoted output figures at 250 horsepower and 340 pound-feet of torque, numerous automotive journalists and testers of the era theorized that General Motors was deliberately underrating the engine’s true capabilities to protect the corporate hierarchy, particularly the flagship Corvette.
In the decades since General Motors ultimately discontinued the Chevrolet Camaro, the automotive giant has largely vacated the domestic rear-wheel-drive sports coupe segment, leaving Ford as the primary standard-bearer with the Mustang. Interestingly, prospective buyers who walk onto a modern Ford dealership lot with that exact same $39,900 budget can acquire a brand-new Premium EcoBoost Mustang that delivers remarkably similar straight-line performance figures, achieving a zero-to-60-mph sprint in approximately 4.5 seconds.
While the vintage Pontiac naturally lacks modern creature comforts and connectivity features like Apple CarPlay, it offers a distinct character and historical significance that guarantees an immense amount of attention at any local car gathering or enthusiast meet.
