Take a moment to appreciate this real-deal 1972 Buick GS 455. This was the final stand for the muscle car before overregulation, and Buick went out with a 455 ci V8 bang. But since these were always low production and expensive machines, a genuine '72 GS 455 convertible like this is only one of less than 210 ever produced.This car isn't just ultra rare; it's stunning, too. So the glossy red paint will draw crowds before you even have to bring up production numbers. It has the kind of luster that comes from an investment in modern professional paint practices, and let's face it, the sunny day nature of a classic ragtop means you want a paintjob that really pops in the sunlight like this one. But even beyond just the color, the GS 455 is one of those desirable classics we all love. The design perfectly blended Buick's upper class image with performance touches like the functional hood scoops, red striping on the rocker panels, and the iconic Buick Rallye wheels. Plus, this was one of the final years before chrome bumpers had to sacrifice style for federal regulation. You see it especially in the rear where the one-piece bumper creates an entire panel that's crafted to integrate the angular rear fenders, low trunk, and the dual exhaust. The overall outstanding condition of this convertible is the result of $18,000 of recent improvements, including a full engine rebuild, that has occurred since 2013.The idea behind a Buick GS is to mix muscle with Buick's reputation for luxury, and that was not forgotten on the interior. Step inside, and there is comfortable seating for up to six on the pristine white vinyl seats. The stereo has the cool original knob-style appearance, but in reality there's a modern AM/FM/CD unit with Bluetooth hidden in the glovebox, so everyone can blast their favorite tunes. This Buick came loaded with features like power windows, power locks, and cruise control. This one is really set up for the driver with items like a three-spoke Buick Rallye steering wheel, round GS gauges in front of that, and auxiliary readouts added below the dash. Looking for the tach? It's an ultra cool optional hood-mounted item for the ultimate '70s style heads-up display. One of the great things about the power folding white top is that you can keep it open to the world nearly year-round. That's because this not only has a heater/defrost, but more importantly, there's also air conditioning converted to modern R-134a. You'll especially want to keep the roof open all the time because you're going to get addicted to the roar of the exhaust note.With such an impressive presentation so far, you won't be surprised to know that this one carries a correct 455 cubic-inch V8. You can see from the exceptionally authentic and well-maintained engine bay that it has been given Stage 1 upgrades. Buick rated these at 270 hp, which might not seems as high as previous years, but that's just reflecting the more realistic net ratings (the '72 GS 455 Stage 1 still blew the doors off anyone who thought a Buick would be easy prey.) You'll have no problem getting all this power to the ground thanks to GM's stout TH400 three-speed automatic transmission and limited slip rear end. But there's another side to this muscle car, too. It's running a very versatile 3.42 ratio, and that combined with the power steering, front disc brakes, and new BF Goodrich tires at all four corners means this beefy Buick can also live up to its luxury cruising legacy.Ultra rare, heavily invested, and exceptionally cool, this GS 455 convertible is the kind of machine that you're going to want to call about today because it's likely gone tomorrow.
