Mercedes-Benz old-timers may have a timeless and imposing design but they were always designed for comfort instead of tire-shredding performance. This 1968 Mercedes 250s W108 however is a whole different animal, as it borrows the driveline and the interior from a 2017 Mercedes-AMG C63S W205!

The highly unusual restomod, courtesy of The AMG_OG is located in Brisbane, Australia, and looks like the perfect sleeper. The owner has kept the original bodywork painted in black with plenty of chrome on the grille, bumpers, headlight surround, and window line. The modern 19-inch five-spoke wheels revealing the huge AMG disc brake and the “S” emblem on the tailgate are the only indications that this is no ordinary W108.

Another thing that strikes you from first sight is the interior, directly swapped from a right-hand-drive W205. The Alcantara-wrapped steering wheel, the modern dashboard with the infotainment screen, and the bucket seats look weird in combination with the Paul Bracq designed exterior.

While cruising on the road or drifting on the track, this Mercedes is confusing bystanders as no one would expect that level of performance from a W108. After all, the most powerful version coming from the factory was the 280 SEL with a 4.5-liter V8 producing 195 hp (145kW / 198PS) sent to the rear wheels through a three-speed automatic gearbox. While this was a hefty amount of power for the ’70s, it is a far cry from AMG’s modern 4.0-liter bi-turbo V8 that delivers 503 hp (375 kW / 510 PS) and 516 lb-ft (700 Nm) of torque in the stock C63s.

The tuned mill in this W108 is even more powerful thanks to upgraded downpipes and custom calibration. According to the tuners, it now produces 514 hp (384 kW / 522 PS) on the wheels, up from the original 393 hp (293 kW / 398 PS) measured on the dyno. We are not sure if the owner has tested its performance, but the stock C63s sedan accelerates from 0-62 mph (0-100 km/h) in under 4.0 seconds and has a top speed of over 180 mph (290 km/h).

The conversion was completed by Deluxe Body Werx, with engine work by Maranello Auto Services and further tuning by eTuners.

Correction: The donor car is a 2017 and not a 2019 C63s
