1979 Mercedes-Benz 300SD

I love a really well-kept Mercedes-Benz W116. Maybe because I own one, but I can’t be alone in feeling this way. These cars feel as solid as anything when everything is sorted and won’t cost you a ton of money to buy and maintain one. All the gas-powered W116s are fine cars and the first ever production turbo diesel car to go on sale in the United States in 1978, the 300SD, was a gem as well. I have a hard time justifying ever selling my 300SD because for the money, nothing can replace it equally and frankly, there is nothing wrong it. So when I see these W116 300SDs come up for sale now and then I always take a closer look to see how other owners treat theirs. Today’s 1979 model for sale in Oregon has me envious and jealous thanks to a few OEM upgrades.

1984 Mercedes-Benz 300SD


The last few W126 Mercedes-Benz I looked have fell more towards the collector car status in this 1987 300SDL with an outstanding interior and this nearly perfect 1987 560SEL. Today’s W126, a 1984 300SD for sale in California, isn’t one of those cream puff cars but it is far from a beaten up example either. This OM617 S-Class has just enough miles where you don’t feel bad about piling on some more but not too many where you feel like an engine overhaul is around the corner. Finished in Lapis Blue with gray leather this 300SD could be the perfect daily driver. What do you think?

1984 Mercedes-Benz 300SD with 11,300 miles

File this one under another great Mercedes-Benz that you usually see with hundreds of thousands of miles on but for whatever reason has almost none. This 1984 300SD shows a crazy 11,300 miles and looks every bit the part. You can totally see why people plunked down almost $40,000 (over $93,000 in 2017 dollars) for these when they are new. It’s frugal, handsome, secure, has enough to power to get out of its own way and all this won’t cost you a fortune to keep going. Except this car, as you might have guessed, will need a small fortune to take home with you.

What is there to say about this car? I overwhelmingly prefer the gen 1 (1981-1985) W126s over the later ones even though they do look a little more dated, but I think that’s the beauty of them. Give me a clean set of 14 inch Bundts with a OM617 and I’m as satisfied as I can possibly be in owning a car. This is a great color combination with the Midnight Blue and tan interior even with those terrible North America spec headlights.

Like I said, all this is going to cost you. $35,000 is a ton of money for any W126 but it’s tough to fault the seller for asking it. The market for clean golden-era Mercedes diesels isn’t slowing down but I wouldn’t bet on this car gaining anymore value once you start driving it. As I’ve said before, miles don’t scare me one bit so I’m really not the guy that this car appeals to.…

1983 Mercedes-Benz 300SD

Powered by the legendary five cylinder OM617, the sort of motor for which Mercedes-Benz earned their reputation as manufacturers of “million mile engines,” the W126 300SD was a classy and reliable ride, offering a frugal option for S-class owners not perturbed by a clackety-clack sound coming from the front end of their luxury car. This engine would be replaced in 1985 by the OM603 six cylinder unit (later enlarged to 3.5 liters) that, while offering more power, was susceptible to a number of very serious problems (a fault with the trap oxidizer – part of the emissions system – that could ruin the turbo, cylinder heads prone to overheating and cracking, bent rods and head gasket failures). So those looking for a diesel W126 would do well to consider an early, first generation car like this one.

1985 Mercedes-Benz 300SD

2Another day, another old diesel Benz. I know, I know. But when I saw this one I couldn’t resist. Yesterday I wrote up an ‘87 300SDL. While that car presented very nicely, in truth the better W126 diesels are either the early, short wheelbase models (’81-’85), like today’s car, or the very late ones (’90-’91), during which time the short and long wheelbase diesels shared the same engines. As noted yesterday, the diesel motors in the cars in the period in between had a few design faults that could potentially affect their longevity (quite unusual for a Mercedes product). This particular car is an ’85, the last year in which you’d find the legendary OM617 engine under the hood.

1982 Mercedes-Benz 300SD

1A W126 diesel provides all the comfort, style and luxury of the legendary S-class while giving your wallet less of a pounding at the pump. There were three diesel engines available for this platform: one five cylinder unit (a 3.0 liter offered in the 300SD between 1980 and 1985) and two six cylinder units (a 3.0 liter offered in the 300SDL between 1986 and 1987, and a 3.5 liter offered in the 350SD/SDL between 1990 and 1991). These later engines were afflicted by a number of reliability problems, quite out of character for a Mercedes diesel product. So if you really want an oil-burning W126, the safest bet is to stick with one of the earlier cars, like this one. Not only does this ’82 300SD have the more reliable five cylinder engine, it’s presented in a particularly fetching and suitably classy shade of green.

S-Classic Showdown: 1979 300SD v. 1977 450SEL 6.9

For some time, the W116 has been stuck in no man’s land value wise; not as new or attractive as the W126 that replaced it, and not as classic a design as the W108 series had been. It’s not that it’s an unattractive car at all, but unfortunately it’s bookended by arguably better looking models and unfortunately – outside of some real stunners – the value of Mercedes-Benz sedans falls below coupes and convertibles. For a classic Mercedes-Benz enthusiast on a budget, then, the W116 offers a lot of vintage Mercedes-Benz build quality and longevity on a budget. There are plenty to choose from, too – lest we not forget this is a S-Class Mercedes, so the price was stratospheric when new and even lightly used. Option out a 6.9 to the tune of around $50,000 in 1980, and you’d have the equivalent buying power of nearly triple that amount today – roughly $143,500 in 2015 money. And they were laden with top-end technology for the time; recently I covered a series of Volkswagen Rabbits, where everything outside of the tires was an optional extra. In the S-Class, you had electric nearly everything, electronic climate control and in the case of the 6.9 you threw in hydropneumatic suspension. These were, and still are, impressive vehicles, many of which were maintained to a high level yet are available for a fraction of their original investment. Today I’m taking a look at the slowest and fastest of the bunch – a 300SD and a 450SEL 6.9. Which is the classic S-Class that woos you?

If you’re looking to conserve fuel, there’s a few ways you can go about it. There will, however, always be limitations to just how green you can be. If you go the hybrid route, you’ll see your gas mileage increase, but in actuality, you’ll still have to fill up with petrol and have a battery replacement years down the line that you’ll have to deal with. What about electric vehicles then? Many of these vehicles have come a long way in terms of range, but you’re still getting your juice from via a plug, which more often than not means energy derived from coal. But what about that old standby, diesel? Sure, it has a bad image in the US from the vehicles we experienced in the 1970s and 1980s. But Mercedes-Benz has stuck by this technology for years and their diesels of today are some of the most advanced on the market.

This 1982 300SD for sale in Ohio couldn’t exactly be considered one of their earlier efforts, as their dabbling with diesel technology dates back to the 1930s. But this W126 was one of those cars that was sold here in this market as we were emerging from the dark days of the 1970s energy crisis. With the tried and trusted OM617 inline-5 cylinder turbodiesel under the hood, you are getting W123 reliability in a larger, more stately package. The ultimate sleeper when it comes to fuel conservation, then?

1983 Mercedes-Benz 300SD with 58k miles

I always wonder why cars that are eco-friendly have to look so overtly different from a normal vehicle, oftentimes appearing as the automotive equivalent of a Birkenstock. Not being one to shout about my accomplishments, I like to do things a little bit more discreetly.

1983 Mercedes-Benz 300SD

Sometimes it’s hard for me to think of the W126 Mercedes-Benz S class as a classic vehicle. When introduced at the dawn of the 1980s, this new model moved the luxury car target in true S class fashion, bringing features such as integrated bumpers, air bags and anti-lock brakes into the mainstream mix. With a new S Class in dealers for 2014, we once again see this big Mercedes charting the course for another generation of luxury sedans. You still see plenty of these W126s still on the road today, a testament to their durability. Many of these you see are diesel models such as this low mileage 300SD for sale in California.
