Imagination and tuning know no boundaries: the tuner S-Klub LA unveiled a super-limousine jewel at the 2025 SEMA tuning show (Nov 4–8, 2025). What happens when the body of a 1971 Mercedes 600 Pullman is placed on a modern Mercedes-AMG S 63 platform? The result: Final Boss 600.

The name says it all: Final Boss 600 — in other words, an S-Class taken to the extreme, paying homage to the famous Mercedes 600 Pullman.
S-Klub LA created a spectacular restomod project in which the elegance of the 1971 Mercedes 600 Pullman’s bodywork is combined with the modern technology of the 2024 Mercedes-AMG S 63 (W223). The Pullman body was adapted to the drivetrain of the AMG S 63; under the hood lies the plug-in hybrid powertrain from the AMG S 63 E Performance, and the interior is also borrowed from the current S-Class generation.
The plug-in hybrid system delivers 1,000 PS and 1,356 Nm, compared to 802 PS and 1,430 Nm for the AMG S 63 E Performance.
Thus, this superstar is equipped with AMG Ride Control+ suspension featuring active stabilizer bars and rear-axle steering.
The interior mirrors that of the S-Class, with a 12.8-inch portrait-oriented OLED touchscreen, a 12.3-inch digital instrument display, the AMG Performance steering wheel, and AMG sport seats upholstered in Nappa leather.
The custom-built Pullman body is painted metallic green, features widened steel fenders, a massive rear wing, LED headlights, and oversized chrome wheels. Compared to the original Mercedes 600 Pullman, this version stands out with an oversized Mercedes logo on the grille, generous air intakes, and additional auxiliary lights.
The 4-liter AMG V8 engine is also visible through the hood, just like on classic hot rods.
S-Klub LA completed this spectacular transformation in less than four months.
The price? S-Klub LA is asking USD 4.5 million, an enormous sum considering that a standard Mercedes-AMG S 63 E Performance costs €223,236 (USD 258,518). For comparison, the Brabus 1000 — a tuned model from Brabus based on the same AMG GT 63 S E Performance — costs €563,534 (USD 652,661).
S-Klub LA is more than just a tuner; it is a private automotive design studio based in Southern California. The extremely high price is justified by the fact that each vehicle built by S-Klub LA is unique. The design studio develops high-quality models from an artistic perspective. They have been active since the mid-1990s and have won numerous international Best of Show awards.
