Mercedes-Benz might be going electric sooner than expected, but the brand, in conjunction with AMG, is still building some of the meanest gas-powered German sports cars around. The brand also enjoys a massive fanbase across the world, and modern Mercedes-AMG performance cars have grown in popularity in the aftermarket tuning scene thanks to their responsive turbocharged engines. One person has gone above and beyond what we're used to seeing in the Merc tuning scene by turning a classic 1968 W108 into a sleeper car with the guts of a 2017 Mercedes-AMG C63S. Forget about legends like the 300SL, this thing is the people's champion.

This custom Mercedes-Benz 250S (W108) has officially broken the internet, and it's easily one of the coolest swaps we've seen in recent years. Built by Deluxe Body Werx, Maranello Autos, and Etuners, this old-school Merc oozes style and packs a killer punch.

Under the hood, the original 4.5-liter V8 that made around 200 hp was replaced with a 4.0-liter twin-turbo V8. A set of upgraded downpipes and a custom tune increased the stock dyno figure of 393 horsepower at the wheels, to a serious 514 ponies. In the C63S, this engine meant a 0-60 time of under 4 seconds and a top speed in excess of 180 mph.

The exterior looks mostly stock with the only exception being those massive 19-inch five-spoke wheels that hide a set of massive AMG brakes. An "S" badge on the trunk lid is one of the few indications that everything is not quite as it seems. The interior is another work of art. It has been directly swapped from a W205 model and includes the modern Merc's infotainment screen and sporty Alcantara steering wheel. The sporty bucket seats look out of place but are a must-have when you're dealing with this amount of power. This is one serious build, and hopefully sets a trend for others looking to build quick and classic Mercedes-Benz vehicles.
