Mercedes-Benz makers of the legendary Unimog since right after WWII have also made usable SUV's like the G model and the more luxurious M Class. Mercedes are famous for the great craftsmanship, strong engineering and lasting a long long time. 500.000 miles or more are not uncommon to see in these trucks.
4x4 Mercedes have impressive off-road capabilities and can be found in jungles, mountains and deserts as military vehicles, fire fighters, expedition campers, and even in competitions and hard racing like truck trials and the tough Dakar Rally.
1992 Mercedes-Benz 300GD G-Wagen G-Wagens are fairly rare in UK, but more and more people are coming to realise how good they are. Once you have had a "G", you don't want anything else, except, perhaps, a Pinzgauer, but Mike test-drives them for a living anyway.
Mercedes-Benz 406 Unimog 1975 Kendall from Canada has just spent 14 month doing a frame-off restore, to original, the biggest changes have been twin 5" chrome exhaust and a lot of chrome powder coating, even though the rig is over 31 years old there is only around 960 hours on rig and less than 6000 miles.
When talking about unmodified, out of the box 4x4's meant for tough conditions and professional use, my money is on the Mercedes/Puch G-class (work variants that is, not so much the bling versions). As a working vehicle, the G-class' off-road and other field capabilities are really second to none. Its overall technical quality and durability are also very impressive and contribute to the supreme overall usability.
Former Fire Trucks - Jim has two former fire trucks. One is a Volvo and the other a Unimog. He takes them to trails in Oregon, Washington and British Columbia. Mostly forested trails and roads.
1988 Mercedes G class 230 GE Alin from Romania takes his G class Mercedes wheeling in Carpathian Mountains ( incredible beautiful landscapes and lots of wild life ); the terrain is a mixture of rocks and mud . He also likes wheeling in Danube Delta area ( it's like you go back in time ).
1983 Mercedes G-Klasse 300gd With more than 650,000 miles on it - this car has worked hard for Merv since he bought it when it was 6months old. It was bought because at that time it was the only car that size that would pull any broken down trucks of his off the motorway fully freighted!
1955 Unimog 411 There are lots of mountains in British Columbia, Canada, on Vancouver island where Allen lives. He uses his Mog to go mud racing, and uses it on his farm to haul wood, etc.
