• 1990 Mercedes 250GD Wolf by Expedition Motor Company

The aftermarket company has restored this ex-military vehicle with new glam, but the same engine and transmission

LISTEN 04:30

The G-Wagen started life being a military truck and was later offered to us civilians as a hardcore off-roader that was matched by vehicles like the Land Rover and the Land Cruiser. The G-Wagen that we know today is fast and powerful, but back in its early days, it was brute and tough. Expedition Motor Company got hold of a 1990 250GD and restored it to perfection. As the company puts it, this is the story of how a rough ex-military war machine becomes a work of art.

What’s Special About This Beast?

Expedition Motor Company is known to restore some fantastic models, and their choice of G-wagens generally are the ex-military models from the early 90s. This particular 250GD is a 1990 model that the German NATO forces used in Afghanistan. The company can build you a more modern version with a hardtop, automatic transmission, etc., but this one you see is as retro and analog as possible.

The aftermarket company dismantled and removed the body from the frame and blasted it down to its bare metal.

It then addressed all the sheet metal issues and applied an anti-corrosive primer. Finally, the exterior finish was applied, wet-sanded, and polished. The color chosen for this beauty’ repaint was sunset orange, which seems a little too bright, but hey, what’s the point of this restoration if it doesn’t scream for attention, right? The restored GD250 is equipped with new wheels and BF Goodrich all-terrain A/T tires as well.

The Expedition Motor Company ripped out the cabin and the wiring harness. A new custom interior with new window seals and gaskets took its place. After all this was done, the body was reinstalled on chassis panels, and this time, hand-fitted to attain proper symmetry. A few new additions, however, made their way into the cabin, like an air conditioner and Clarion stereo system with four speakers.

The Core Required Extensive Work

This example is powered by the original OM602 engine that Mercedes produced from the 1980s to late 1990s. The five-cylinder diesel mill is considered one of the most reliable engines ever built.

The naturally-aspirated engine made just 93 horses and 117 pound-feet of torque.

It was mated to a five-speed manual dogleg transmission. One of those, however, was a crawler gear.

While Expedition Motor Company decided to retain the engine instead of going for a new one, it still required severe restoration. The company tested the cylinder compression and oil pressure before cleaning and dismantling it. The engine block was cleaned, prepped, and refinished, while the cylinder head and camshafts were inspected for wear.

The engine needed quite a few new parts. This included new front and rear crankshaft seals, cylinder head bolts, cylinder head gasket, timing belt, water pump, oil pan gasket, and timing belt tensioner pulley. The transmission was disassembled and fitted back with a new clutch, transmission seals, throw-out bearing, refinished gearbox housing. The transfer case was inspected and reassembled with new gaskets and seals.

The suspension system, too, needed a complete overhaul. New springs, shock absorbers, urethane suspension bushings, and tie-end rods were installed. The company aligned the suspension steering and installed new steering dampers, too. The company installed new brake lines, new fuel lines, and new body mounts. The calipers were rebuilt, the drums reconditioned, and finally fitted back with new brake pads, shoes, and rotors. Expedition Motor Company went through the same disassemble-inspect-reassemble process for the differentials and axle housings, too.

How Much Does It Cost?
