I have to admit, when I first saw the Hagerty crew roll into Brown & Miller Racing Solutions in Concord, North Carolina, I thought the story would be all about racing plumbing. BMRS makes ultra-strong Kevlar hoses, wiring, and fittings for some of the biggest names in motorsport, so the shop tour could have easily turned into a tech deep dive. But behind one unassuming door sat something far rarer: a nearly new Buick GNX with just over 1,000 miles on the odometer. That is the kind of surprise that keeps me hooked on barn-find and survivor-car hunting.

🏁 The Buick GNX: Number 321 of 547

I have been around muscle cars long enough to know that a Buick GNX is not just any Grand National. The Grand National was already infamous in the 1980s, but the GNX was the final no-excuses version. Buick partnered with McLaren for the 1987 model year, and only 547 left the factory. Each one received a bigger turbo, a new intercooler, upgraded suspension, and revised heads. The result was more than 300 horsepower and nearly 400 pound-feet of torque, which was massive for the late 1980s. In the real world, these cars could outrun some European exotics, and they looked mean doing it.

This particular car is number 321, and the host made a strong case that it might be the lowest-mileage GNX left anywhere. It was originally bought in Michigan, later owned by an older couple in Pennsylvania, and eventually discovered through a chance connection. The condition is collector-grade survivor stuff: original paint, original interior, original inspection stickers, and even that new-car smell inside. The seller's biggest complaint? A fading factory label. That is the whole list.

Here is a quick refresher on why the GNX is such a big deal:

• Build count: 547 total for 1987

• Odometer on this example: just over 1,000 miles

• Build number: 321

• Factory rating: 275 horsepower

• Real-world reputation: far more punch, especially in torque

🚗 The 1968 Camaro Rally Sport: A Family Heirloom

While I was still processing the GNX, the day got even better. A local friend named Butch King brought out his own time capsule: a 1968 Camaro Rally Sport that has been in his family since new. Butch bought it when Chevrolet's second model year was still hitting showrooms. His wife was eight months pregnant at the time, and their son actually came home from the hospital in the Camaro. That is not the usual family-hauler story, but it is exactly why this car resonates with me.

Over the decades, Butch used the Camaro as both a family car and a personal toy. It racked up more than 140,000 miles before being taken off the road in the 1990s. As a professional body man, he kept the car alive with his own skills. He saved countless original dealer parts, many still in their wrappers, and even widened a set of Super Sport wheels for a tougher stance. After all those years in storage, the Camaro is still solid and waiting for its next chapter. Butch plans to restore it himself and eventually pass it on to his son, which keeps the family connection alive through one of Chevrolet's most iconic muscle cars.

These two cars live at opposite ends of the collector spectrum. The GNX is a low-production, race-bred survivor with factory originality and a barely touched odometer. The Camaro RS is a family heirloom with real mileage and decades of personal history. But both remind me that the best finds are not always sitting on an auction stage. Sometimes they are tucked behind a shop door or stored in a garage, waiting for someone to look closely enough.

As of 2026, that is what keeps me watching these shop tours. I thought the story would be about race car plumbing, but it turned into a muscle car history lesson with two unforgettable machines. One is a 1,000-mile time capsule that represents Buick's late-1980s knockout punch. The other is a Chevrolet that carried a newborn home and still has a future with the next generation. I cannot think of a better way to spend a few minutes with car people.
