I was scrolling through an auction listing the other day, watching a 1987 Buick GNX cross the block for a quarter-million bucks, when it hit me: we’ve all been punked by rarity. The GNX is the automotive equivalent of a Fabergé egg—gorgeous, stupidly expensive, and hidden away in a vault. Meanwhile, its rowdier, cheaper sibling, the Grand National, did all the actual street fighting back in the ’80s and still offers way more laughs per dollar today. Let me break down why the working-class hero is the one you really want.

First, a quick spec throwdown. In 1987, Buick handed a handful of partially finished Grand Nationals to ASC/McLaren, who bolted on upgraded turbos, ceramic-coated headers, a bigger intercooler, and a tasty suspension setup. The result was the GNX: 276 horses and 360 lb-ft of torque, sprinting the quarter mile in 13.5 seconds at over 100 mph. That’s seriously quick, even by today’s standards—think early Porsche 930 territory. But here’s the punchline: the regular Grand National that same year made 245 horsepower and 355 lb-ft. A gap of just 31 ponies and 5 lb-ft. On the street, that’s the difference between a firm handshake and a slightly firmer handshake.

Now let’s talk money, because my wallet has feelings too. A GNX in 2026 will set you back an average of nearly $203,000, with top-tier cars breaking $250,000. That’s Lamborghini money for a Buick that, let’s be honest, is still fundamentally a puffed-up Regal. On the flip side, a clean, driver-quality Grand National hovers around $44,000, with plenty of solid examples in the $30k–$40k range. For the price of one garage queen that’ll give you anxiety attacks every time a bird looks at it, you could buy four or five Grand Nationals and start your own biker gang of turbo V6s. Which one sounds more fun at a stoplight?

And this is where the Grand National truly earns its crown: tuneability. The turbocharged 3.8-liter V6 in the GN is a boost-hungry monster. Slap on a larger intercooler, a free-flowing exhaust, bigger injectors, and a modern ECU chip, and you’re easily pushing 300+ horsepower. Throw sticky tires into the mix, and you’ll be deep in the 12-second quarter-mile range—essentially matching or even embarrassing a stock GNX. The GNX, meanwhile, is often treated like a holy relic; you can’t so much as change the air filter without a collector sobbing into their appraisal guide. The Grand National, though, begs to be modded, raced, and occasionally driven like you stole it.

Culture-wise, the GN was the heavy hitter. During the late ’80s, Grand Nationals were everywhere—drag strips, mall parking lots, underground street races. They developed a reputation as the car that would bully your buddy’s 5.0 Mustang while looking like Darth Vader’s company sedan. The GNX, by contrast, was so rare (only 547 units built) that most people never even saw one outside a magazine. You didn’t fear the GNX because you never encountered it; you feared the Grand National because it was always lurking. It showed up in music videos, TV episodes, and movies as the quintessential “bad guy” ride. That cultural footprint is practically tattooed on car culture’s arm.

Fast forward to 2026, and the contrast has only sharpened. GNX values have soared so high that most examples now live in hermetically sealed bubbles, emerging only for concours events and Instagram shoots. They’ve stopped being cars and started becoming investments. The Grand National, bless its blacked-out heart, remains a driver’s car. Parts are abundant, aftermarket support is massive, and the community is full of folks who actually use their Buicks. You can still find a clean one, bolt on a big turbo kit, and humble modern sports cars without torching your kid’s college fund.

And can we talk about the sheer joy of the Grand National’s aesthetics? That all-black everything—paint, grille, bumpers, wheels—makes it look like it’s going to a funeral for your ego. It’s a car that whispers, “I’m here to ruin your day in the classiest way possible.” The GNX wears the same designer suit, but it rarely leaves the house. The Grand National? It’s the one at the diner at 2 a.m., ready for mischief.

So yes, the GNX is a legend, an icon, a unicorn with a turbo. But if you actually want to remember why Buick’s turbo V6 program was such a big deal—if you want to feel that surge of mid-range torque, hear the turbo spool, and turn some tires into smoke—the Grand National is the only choice that makes sense. It’s the car that built the legend, not just inherited it. And the next time I see a six-figure GNX auction result, I’ll smile, crack open a beat-up Road Track from 1987, and think about all the Grand Nationals still roaming the streets, ready to school the next generation of unsuspecting muscle cars.
