Video: S-Klub LA “Final Boss” Mercedes 600 Restomod Packs 800+ HP Hybrid Power

At first glance, it looks like a restored 1971 Mercedes-Benz 600. Look closer, though, and things start to feel… off. In a deliberate way.

S-Klub LA calls this creation the “Final Boss,” and it was built for SEMA 2025. Underneath the classic W100 sheet metal sits something far newer—an entire 2024 Mercedes-AMG S63 E Performance platform. Not a modernized suspension. Not just an engine swap. A full chassis transplant.

The Engineering

The donor S63 reportedly carried a sticker price worth of $200,000 and had just over 4,000 miles before the teardown began. Instead of modifying the 1970s chassis to accept modern hardware, S-Klub LA noticed that the wheelbase of the short-wheelbase W100 and today’s long-wheelbase S-Class (V223) are almost identical. That similarity made a complete swap viable.

The original 1971 shell—a Texas barn find that had been rotting for a decade—was restored and then lowered onto the ultra-modern AMG structure.

Mechanically, the twin-turbocharged 4.0-liter V8 remains intact, paired with its electric motor. Output is listed at more than 800 horsepower and over 1,055 pound-feet of torque. The hybrid drivetrain stays fully functional. Even the power windows reportedly work. Suspension, brakes, and the entire electronics suite made the jump as well, including MBUX, massaging seats, and the full suite of driver-assistance systems.

Open the door, and instead of vintage wood-trimmed opulence, you’re met with a fully digital, contemporary cockpit inside a comparatively tight classic cabin.

Exterior

Visually, the body has been widened to match the AMG’s track width. The original W100 headlight housings were 3D-scanned, digitized, and re-engineered to house the S63’s modern LED units, complete with functional air intakes. The car wears a deep green finish, offset by tinted exposed carbon fiber on the roof, mirrors, and aerodynamic add-ons.

Then there’s the rear wing, which is a massive fixed JDM-style piece. And up front, an oversized Mercedes emblem sits planted in the center of the grille.

The Reaction

Online reaction has been split, with some people praising the craftsmanship and ambition. Others… not so much.

User @thewedge8823 wrote, “Get rid of the rear spoiler and the emblem in the middle of the grille, and it would be clean.” @gunnshell was more direct: “The rear spoiler is absolutely hideous.” Meanwhile, @indybo770 said, “The wing does not fit the build at all.”

A retired mechanical engineer, @robertmoss9468, applauded the boldness but suggested he would have handled some solutions differently. Others compared the styling to “small-town homebrew tuning” or even a “wannabe Bentley.” And @dinyarmaster2350, quoting Kenny Rogers, summed it up this way: “You’ve got to know when to hold ’em and when to fold ’em—but you went all-in and lost the bet on this one… sometimes less is more.”

From a technical standpoint, merging 1971 sheet metal with 2024 engineering is undeniably remarkable. Everything reportedly functions as intended. Whether it’s beautiful—or too much—is clearly a matter of taste.
