In the world of restomods, subtlety usually goes to die. But what the Californian tuning house S-Klub LA has pulled off with its latest creation, Final Boss, isn’t just unsubtle—it’s audacious in the way only a moonshot engineering project can be. Take a stately Mercedes-Benz 600 (W100), the rolling throne once favored by dictators and tycoons, and surgically graft it onto the bleeding-edge underpinnings of a Mercedes-AMG S63 E Performance. What you get is a car that looks like it escaped from a fever dream but drives like a modern super-sedan on steroids.
This isn’t your garden-variety “drop in a crate motor and call it a day” restomod. S-Klub LA founder Ed Sarkisyan didn’t just modernize the W100—he effectively reincarnated it. After buying a factory-fresh S63 for north of $200,000 and putting about 6,200 kilometers on it, Sarkisyan and his team tore it down for parts. Meanwhile, a long-forgotten 1971 Mercedes 600 shell, discovered rotting in a Texas warehouse, was painstakingly resurrected. The twist? The old body didn’t have to be forced to accept new bones—the wheelbase of the classic W100 and today’s long-wheelbase S-Class (V223) is eerily close. So the team ditched the seventies chassis entirely and dropped the restored 600 body onto the complete modern S63 platform.
What lies beneath that regal, boxy silhouette is pure 21st-century insanity. The Final Boss packs the S63’s 4.0-liter twin-turbo V-8 paired with an electric motor, good for more than 800 horsepower and a truly obscene 1,424 Nm of torque. That’s hypercar output in something that, at a glance, looks like it should be chauffeuring a Cold War-era head of state. And it’s not just the powertrain that made the jump. The adaptive suspension, massive AMG brakes, and the full electronic nervous system came along for the ride, including the MBUX infotainment suite, massage seats, and a full menu of driver-assistance tech.
Crack open the door and the time warp becomes complete. Where you’d expect polished wood, chrome toggles, and the smell of vintage leather, you instead find a fully digital AMG cockpit, crammed into the relatively narrow greenhouse of a 1970s limousine. It’s as if someone hid a modern S-Class inside a museum piece—and then gave it launch control.
Outside, subtlety was clearly not on the design brief. To match the S63’s wide track, the 600’s bodywork has been aggressively flared. The headlights are a particularly wild bit of nerdy craftsmanship: the original W100 housings were 3D-scanned, digitally re-engineered, and then adapted to swallow the AMG’s modern LED units, complete with functional air intakes. The deep green paint is offset by exposed carbon fiber on the roof, mirrors, and aero trim, giving the old-money silhouette a distinctly new-money edge.
And then there’s the internet, doing what the internet does best. While many enthusiasts are in awe of the sheer engineering effort—calling it “next-level” and “a work of art”—others are clutching their pearls over the styling, especially out back. The massive, JDM-style fixed rear wing and the oversized Mercedes star in the grille have become lightning rods for criticism, turning the Final Boss into a rolling comment-section war.
But that, in a way, is the whole point. The original Mercedes-Benz 600 was never meant to be tasteful—it was meant to be the biggest, baddest luxury car on the planet. S-Klub LA’s Final Boss simply updates that mission for an era of 800-horsepower hybrids and carbon fiber. Love it or hate it, this is what happens when a classic icon meets modern excess head-on—and refuses to blink.
