Just when you thought the Mercedes G-Class couldn't get any more capable, AMG launched the bonkers six-wheeled G63 6x6 during the off-roader's previous generation. Production was limited to only around 100-160 units, so opportunities to own one don't happen very often. A custom-built G63 6x6 is heading to auction this month and is expected to fetch over $1 million.

Toyota, on the other hand, never built a 6x6 version of the Land Cruiser. To fill the void, Australia's JMax Engineering created this crazy custom Land Cruiser 6x6 to conquer the Australian outback. It started life as a 2019 Toyota Land Cruiser GLX 70 Series Cab Chassis before being converted into an obscene six-wheeled off-roader.

As part of the conversion, the chassis has been upgraded with a custom brace kit, heavy-duty adjustable lower control arms, and a brake line and bracket kit. Other upgrades include a 6x6 bolt kit, a floating axle kit, a heavy duty jack shaft, Rear Fabricated differential housing, and an adjustable rear sway bar and link kit. A front-mounted bulbar also gives the Land Cruiser a meaner look and the suspension has been lifted by two inches to increase the SUV's ground clearance. It rides on 16-inch rims wrapped in 265/70 R16 tires at the front and 265/70 R16 tires at the back.

Under the hood of the Land Cruiser 6x6 is a turbocharged 4.5-liter V8 diesel rated at 202 horsepower and 317 lb-ft of torque, paired with a five-speed manual transmission. That's less powerful than America's Land Cruiser, which packs a 5.7-liter V8 producing 381 hp and 401 lb-ft of torque.

It also only has 12,212 miles on the clock, so it's begging to be taken on an off-road adventure. Since it was built in Australia, this Land Cruiser 6x6 is offered in left-hand drive only. Given the extensive modifications, this custom off-roader isn't cheap. It's currently listed for sale on Drive for $189,990 - that's around $145,297 at current exchange rates excluding import fees.
