1988 Mercedes-Benz 300GD

An entire generation vehicles has passed since the introduction of of the Mercedes-Benz Gelädewagen in 1979. Time marches on and even though there have been rumors over the past decade of this off-road vehicles imminent demise, this beast continues to soldier on, looking not too dissimilar from the day it debuted. Even though SUVs have been wildly popular here in the US for the last two decades, it wasn’t until 2002 that Mercedes-Benz gifted us this vehicle, as the only G-Wagens to arrive here before that were imported via Europa Motors in Santa Fe, New Mexico. This 1988 model has been worked over, with a 300SD motor installed and a specialty gearbox with low range. Painted in dark green with flared fender arches and a snorkel, this G looks ready to tackle just about anything that stands in its way.

I have 1 more G1/18-5/6.15 Mercedes Gaggenau cast-iron 5-speed gearbox available. Top Gear contacted me to have this G appear in their program!

Before Mercedes-Benz starting importing them officially, Geländewagens used to command high values, even when used. Today, the market for them is still strong, but I’m not sure if it is quite as strong as the asking price on this particular 300GD. While it has an impressive amount of equipment and work done to it, I’d estimate we might be about $5,000 to $10,000 too high, as I’ve seen similar vintage two-door Geländewagens on offer in that range. I could be wrong, however, as there are certainly G-wagon devotees out there who are willing to lay down a lot of cash for what amounts to one of the most capable off-road vehicles ever built.

  1. I’m confused. Why would you take a diesel engine out of 1985 car and put it in a 1988 car that already had a diesel engine? If the ’85 donor car had 160,000 miles on it when the engine was taken out, why are you saying that the ’88 car currently has 97,664 miles on it with the ’85 160k engine?

  2. Why do all that apparently high quality work to an already really nice G-wagen, charge a small fortune for it, and stick it with an older higher-mileage engine? You’re right, David, it doesn’t make a lot of sense. Then again, I don’t know much about these trucks or all that off-road kit. Maybe it makes more sense if you’re into that market.

  3. I may be wrong, but I think it may be because the ’85 engine was a turbodiesel and the original engine was normally aspirated. But again, I could be wrong…

    I’m not an offroad kind of guy, but I do like this truck. However, I do not have enough knowledge or understanding to make any comments on the pricing. Someone with more experience in this market will have to chime in.

  4. If my research is correct, the 300GD G-Wagen came with the OM617 3.0 L Diesel I5, 88 PS (65 kW) (110hp) at 4,400 rpm, 126 lb·ft (172 N·m/2,400 rpm) engine. The ’85 donor engine from a 300SD was a OM617.951 123 PS (125 hp/91 kW) 180 lb·ft (244 N·m) which had a turbo. So a slight increase in hp and torque. I’m not knowledgeable about MB diesel engines, but that seems like a lot of work for not much of a gain.

  5. Turbo + Diesel = Perfection. It’s worth it. Also some generations of MB Diesel’s were rod benders, others were bomb-proof. I trust this owner did his homework, awesome truck.
