Mercedes stopped selling the G63 6×6 nearly three years ago. But the gargantuan vehicle evidently left a lasting impression. And aftermarket customizers have been only too happy to step into its shoes… all six of them.

That includes Kahn Design and its Chelsea Truck Company, which arrived in Geneva this week with the monster truck you see here.

Called the Flying Huntsman 6×6 Civilian Carrier, it draws on similar Kahn projects we’ve seen to date, but adds in a considerable dose of luxury – and room for a rather large family (or two).

To start with, it’s some 880 millimeters (nearly three feet) longer than the Land Rover Defender 110 on which it’s based. And as you can see, it also has six wheels: retro-style 18-inchers in matte black with red accents, shod with Cooper LTZ tires. And all of them are driven, with locking differentials and a high-ratio transfer case.

What separates the “Civilian Carrier” as it’s called from other such conversions is what the Chelsea Truck Company – which specializes in luxing-up utilitarian SUVs – has done to the expanded interior.

The cabin space boasts nine seats to make anything this side of a Ford Excursion look cramped. There’s more leather inside than an S&M convention, covering everything from the headliner and the instrument panel to the grab handles and knee pads. Pretty much everything is covered in what used to be cows, save for the machined aluminum pedals and the rubber floor mats. The windows are tinted but the roof is almost all glass.

The cost of the conversion? A tear-jerking £249,995. That’s almost $350k at current exchange rates – or about enough to buy a fully loaded, top-of-the-line Range Rover SVAutobiography, and still have enough to buy a nicely equipped Range Rover Sport to go with it.
