Autotopia LA/YouTubeHave you ever wondered what a 800hp custom Mercedes-Benz 600 Frosser would look like? It sounds like the work of fiction, but it isn't, and thanks to Shawn Davis from Autotopia LA on YouTube, we've been able to take a look at one truly outrageous car.The car was built by S-Klub LA, led by John Sarkisyan, and the covers were taken off it at the 2025 SEMA Auto Show. This is a restomod done to the extreme, taking the body from a 1971 Mercedes 600 Grosser W100 and mating it to a new chassis and powertrain.The chassis and powertrain chosen were from a brand-new 2024 Mercedes-AMG S 63 E Performance, and thanks to this meeting of old and new, the car now produces 1,000hp hp; its creators have dubbed it the 600 'Final Boss', and it is very easy to see why it earned that nickname.AdvertisementAdvertisementDavis is lucky enough to meet the team behind the car, as well as have a chance to ride in the Mercedes and get to experience just how much power it produces and the savagery of it. This is one of the craziest Mercedes restomods we have ever seen.How This Mercedes 600 Grosser Was CreatedUnlike the other builds that S-Klub have done, the body is not a fiberglass recreation. It is an original 1971 Mercedes 600 body that was previously on a car that once belonged to a mayor in Texas. Underneath, though, it was a rust bucket, but the body itself was in solid condition.So they took the body off the Grosser and mated it to a 2024 Mercedes-AMG S 63 E Performance to create an amazing blend of modern powertrain and classic body. Some parts of the 2024 Mercedes were used, such as the front and rear bumpers, while other components like the headlights were custom-made, and those took six months.The grille was 3D printed, and it incorporates a mixture of the modern Mercedes design, with hints of the original 600 Grosser as well. The roof, side skirts, and other bits of the trim are made of carbon fiber, while there is an opening in the hood to let you see what is powering this monstrous creation. It is a neat touch, and it reminds you that this is a very special Grosser.What Is It Like Inside the Custom Mercedes?Autotopia LA/YouTubeEqually as impressive as the exterior is the interior of the Grosser. The trunk is particularly crazy, showcasing part of the sound system, and incredibly, S-Klub fitted a Louis XII Cognac Classic Decanter into the trunk, worth over $4,600. Hidden underneath the carpet is the Mercedes hybrid system.AdvertisementAdvertisementIn the main cabin, it oozes modern Mercedes. No, really, there are no indications that this is anything other than an S 63 E Performance, as the interior looks virtually identical to the donor car. The biggest change is the lit headliner above your head when you sit down. But it has all the mod-cons, such as the infotainment system, digital dashboard, air con, etc. Close the doors and you really feel like you are in a modern Mercedes.This Is What It Is Like To Drive the Final Boss GrosserAutotopia LA/YouTubeUnsurprisingly, this car is an absolute monster to drive. With such an incredible amount of power on hand, the car really does rip when you put your foot down. But equally, it can be sedate and civilized, with all the comfort and luxury of a modern Mercedes-Benz. Davis even commented that it just feels like an S-Class, but from the outside, it looks like something from another planet.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
