Junkyard Find: 1981 Mercedes-Benz 300TD Wagon

The oldest Mercedes-Benz W123 diesels are getting pretty close to 45 years of age, which means that— finally— they’re wearing out and becoming easy to find in the big self-service car graveyards that I frequent. Most of these proto-E-Classes sold in North America were sedans, but the wagons developed something of a cult following and I keep my eyes open for discarded examples.

Here’s an ’81 300TD turbodiesel that seems to have been going strong when it got crashed.

Crunch! In an instant, this wagon lost 95 percent of its resale value. Repairs could have been performed, but the price tag of all the extensive bodywork would have dwarfed the cost of another daily-driver-quality 300TD.

By diesel W123 standards, this car was just getting broken in when the crash happened. Junkyard shoppers tend to grab the instrument clusters out of these cars soon after they hit the yards (for later sale on eBay), so I don’t always get to see the final mileage figure.

Mouse poop and peach pits abound in the engine compartment, so I think this car sat outdoors for a few years after the crash.

This may be the most reliable car engine ever made, period: the OM617 five-cylinder diesel. This one is the frivolously powerful turbocharged version, rated at 119 horsepower and 170 pound-feet; the naturally aspirated version made… well, if you have to ask, you’re not sufficiently patient to drive one.

Because the seats have the immortal MB-Tex fake-leather covering, they show few signs of wear. If you had all your clothes made out of MB-Tex, you’d never need to get a new outfit as long as you lived.

Maybe 15 years ago, many of these cars got destroyed by attempts to convert them to run on waste vegetable oil; if you know what you’re doing, this conversion works very well. Unfortunately, most who took on such projects didn’t know what they were doing, and plenty of diesel Benzes met premature deaths.

  • Peeryog Everytime I see one I am reminded of the current Santa Fe. And vice versa.
  • Original Guy I watched that Moscow parade thing. (With the Cyrillic captions because my Russian is a little rough.) I won't give the whole thing away, but it started off with a couple of dudes riding around in stupid useless convertibles, standing up like Hitler, who I'm pretty sure was an actual Nazi. They drove around in circles and kept stopping to ask if anyone had seen all the missing military equipment, and all the guys kept moaning back, that no, they hadn't, ask the next section of guys.They looked around for someone shorter and sicker-looking than Putin but they were unsuccessful so they let him speak.The North Korean military was there, I guess the invasion has begun. The North Korean guys were skinny but their rifles were nicely polished, I guess they have plenty of time on their hands between meals.Some of the Russian military guys carried little white flags, I assume they keep those handy in case they run across any U.S. Marines.
  • Marc J Rauch EBFlexing on ur mom - Ethanol is compatible with more types of rubber, plastic, and metal than gasoline and aromatics. This means that ethanol is less corrosive. The bottom line is that long before ethanol could have any damaging effect on any engine component, gasoline and aromatics would have already damaged the components. And the addition of ethanol doesn't exacerbate the problems caused by gasoline and aromatics; it actually helps mitigate them.
  • Original Guy Today I learned that a reverse brake bleeder (and a long borescope) can be helpful if you are autistic and don't have any friends and no one wants to work with you to bleed your brakes. Also it is quick, once you figure out the process.When Canada assembled my truck back in circa 1995, they apparently used a different clip to attach the brake pedal (and switch) to the brake booster than what is technically called for. It is tough to realize this when the spring steel clip flies off to who knows where. Of course I ordered the wrong clip trying to match the style that I saw buried up in the dash before it flew away. My truck now has the 'correct' clip, everyone can relax.I ordered some more brake fluid (DOT 3, nothing fancy) but it turns out I still have two fresh bottles (my shelves aren't empty, I just have too many shelves).Went to install my fancy new Optima YellowTop battery and it turns out I need a new side post terminal bolt. (Yet another order placed, bring on THE TARIFFS.) It would be a shame to strip out the threads on a nice new battery, no?Good news: The longer it takes me to get my truck started again, the more I save on fuel. 😁
