If you can afford blowing more than half-a-million on a new set of wheels with a high ground clearance, then we’re guessing you probably have your sights set on one of the Lamborghini Urus, Aston Martin DBX, Bentley Bentayga, Rolls-Royce Cullinan or Range Rover SVAutobiography.

But why be seen in one of the above when you could choose this 2017 Mercedes-AMG G63 instead? It’s called the Big One for good reasons, as it was extended by 75 cm (29.5 in) by FAB Speed, which had it on display at the 2017 Geneva Motor Show.

A collaboration between the tuner and StretchCars, it rocks updates on both ends, as well as side skirts and fender flares, while riding on massive 23-inch wheels, with power being provided by a twin-turbocharged 5.5-liter V8 that pushes out 563 horsepower.

The longer wheelbase, which inevitably led to the extension of the front and rear doors, roof and other parts, has opened up a gigantic amount of room for rear occupants, who get a couple of captain’s chairs, armrest, foldable tables and a lot of privacy.

The front and rear compartments are separated by a wall, with integrated air vents and a couple of tablets, and everything has been wrapped in fine beige leather incorporating a diamond pattern. Premium sound system, headphones, cup holders and a clock are also included.

Only 10 units of the stretched G63 saw the light of day, all of them based on the previous generation of the G-Class, and now one of them is up for sale. It’s listed by AutoSeredin in Germany for €499,800 (equal to $557,116 at current exchange rates), tax included, down from the initial €593,810 ($661,907). It has 600 km (373 miles) on the clock and as you can see for yourself in the gallery, packs a lot of amenities.

So, has it convinced you to break the bank?
