The Best GTO You Can Buy
Muscle, Style, and Modern Touches—The 1964–67 GTO Still Has It All
The origin of the GTO—one of the most iconic muscle cars in American history—is rooted in a little rebellion. At the time, Pontiac’s Chief Engineer John Z. DeLorean was looking to build something that went beyond the brand’s usual mild-mannered image. His vision: take a humble mid-size Tempest and drop in a big V8. Simple idea. Big impact. That early idea took shape in 1963, when DeLorean’s team realized the Tempest’s engine mounts could accommodate the 389-cubic-inch V8 borrowed from the full-size Bonneville. The test mule? A LeMans coupe fitted with a four-barrel carburetor and heavy-duty four-speed. The result wasn’t just quick—it was flat-out fun. They called it the GTO, a nod to Ferrari’s Gran Turismo Omologato, but this was no sleek Italian thoroughbred. It was a rowdy, customizable street machine—and it hit a nerve with buyers. By 1966, the GTO had become its own model, cementing its place in muscle car lore.
Each year from 1964 through 1967 brought refinements in performance, style, and comfort. And while performance was key, many enthusiasts appreciated the small upgrades that elevated the driving experience. The base models started with a 325-horsepower version of the 389 paired to a three-speed manual—solid, but ripe for upgrades. Tri-Power setups, four-speeds, and other bolt-on performance options made the GTO a tailor-made experience for each owner.
Much like it was back then, today’s restorers still enjoy the freedom to build their GTO their way. That’s especially true when it comes to adding modern features without losing the car’s vintage vibe. One standout option is the RetroSound RetroRadio for the 1964–67 GTO. It includes the Motor 4 for Bluetooth streaming and hands-free calling, all wrapped in a factory-style face that fits seamlessly into the original dash—no cutting, no compromise.
And it's not just about the dash. If you're restoring a 1964–1967 model, you’ll want to consider adding a dual voice coil dash speaker —a great upgrade that allows for stereo sound through a single speaker location. Better still, the RetroSound RetroRadio offers serious audio control while retaining a period-correct aesthetic.
Back in 1964, Pontiac built over 32,000 GTOs as part of the LeMans line. When buying or restoring one, documentation matters. That’s where the Pontiac Historical Society can help—providing factory records that confirm which options a car was originally equipped with. Useful when restoring, and even more so when reselling.
By 1966, the GTO had stepped into its own identity. That year alone saw nearly 100,000 sold—thanks to aggressive styling, big performance, and growing street cred. The 389 still delivered, but in 1967 it gave way to the 400-cubic-inch V8, which became a mainstay for Pontiac muscle for the next decade. It’s also worth noting that the 1967 model introduced the legendary Turbo Hydra-Matic automatic transmission, a massive leap over the old two-speed Powerglide.
Inside, the cars were also evolving. In 1966, GM introduced Strato bucket seats, more ergonomic dash controls, and a more comfortable overall layout. And in 1967, safety took a leap forward with features like a padded dash, collapsible steering column, and front disc brakes. For anyone doing a serious restoration, these are good years to target.
Of course, style remained just as important as performance. From taillight louvers in '66 to the updated grille and integrated rocker trim in '67, Pontiac made sure each year had its own look. These changes are key for restorers aiming for authenticity—right down to the antenna. Thankfully, RetroSound offers exact-fit fender-mount antennas for the GTO that are designed to bolt right in, with no cutting or fabrication needed.
So what’s the best GTO to buy? That’s always up for debate. The 1966’s grille and taillights have a special charm, but the added safety and power of the 1967 make it hard to beat. And with parts readily available—from dash speakers to kick panel speaker pods—restoring either year can be more enjoyable and less of a scavenger hunt.
No matter which year you choose, the first-gen GTO is one of those rare cars that offers timeless style, raw performance, and a healthy dose of history. Whether you're hunting for a numbers-matching showpiece or building a weekend cruiser with hidden upgrades like a RetroSound premium dual voice coil dash speaker, the best GTO is the one you can drive—and enjoy.
