I have located a 1979 300d with a 4 speed on the internets for 900 bucks. I have a 1977 300d (auto) already so I have an idea of what I am getting myself into.

Apparently, the interior is shot and the sunroof leaks (already looked it up, feel that I can fix that easily) but it "runs and drives good"; I figure there is more wrong with it for that price though.

Obviously, oil leaks, electrical and and suspension are all something I will check, but what else?
I know what to look for in an automatic transmission (violent as hell 1->2 shift) but I have no clue with a manual. This is compounded by the fact that I can not drive stick, which is part of the reason I want it. So what should I, and more importantly my manual capable friend who will be with me, look for?


An added bonus is that it will begin the process of getting newfangled BMWs (e39 + e46) out of my life.

Well, one of the reasons I want to learn manual is so I can drive the 35' 1956 GM bus I own with a friend; it requires double clutching the 50 pound clutch and shifting requires a person to be angry. If anything is going to put me off of driving stick, it will be that thing.

Also, the auto transmission in my 1977 300d is dying; it slips going up almost every incline at this point. The transmission will be replaced/rebuilt once I sell off the BMWs. In the mean time, a working 300d will be fast as hell in comparison.

You could do what I saw on a 300D that I looked at buying. They cut bigger holes into the dash and mounted ~5" speakers. It sounded pretty good but looked like complete poo poo. :v:


I purchased the car I mentioned earlier, they listed it as a manual 300D but it turned out to be a 240D. I need more practice driving stick but the car is not reliable enough for me to put ~500 miles a week on it.

I sold one of the 2 new fangled BMWs in my life and turned around and purchased a well kept 1985 300D Turbodiesel. I am digging the turbo, I sense that I will not purchase a naturally aspirated diesel ever again.

edit: On a side note, every single person that has driven the manual 240D likes how easy it is and have remarked that it is a great car to learn on. :colbert:

If the car has been maintained decently, the car will easily hit 500k; if not, you will be in for major repairs.

I am doing my own wrenching and learning in the process. Buying a car that is over 2k will have less need for wrenching, especially over 3k. In the end you will spend at least ~2k, one way or another, for it to be reliable.

The manual 300D was only offered in Europe, the last one I saw on ebay was over 6k simply because it is so coveted. It is possible to convert a 300D to stick, taking a transmission from a 240D. The turbo 300D might not be the best candidate for a manual conversion iirc.

If the car has vacuum issues stay the gently caress away from the 1985 300D, there is a lot more voodoo magic than previous years. The 240D is easier to wrench on since it has way less magic under the hood but, as previously mentioned, it has a severe lack of power.

The w123 ran from 1977 to 1985 but in 1980 or 1981 they changed things. The engines got more power, things moved around in the engine bay, etc.

Instead, the car decided to not start Friday night. According to friends, more mechanically inclined than I am, there is a noise from the compression stroke on a cylinder. There also is oil at the rear of the engine, the aforementioned friends suspect the head gasket.

I expect to do a compression test next week, when I have time. Following that, I expect to take the intake/exhaust off to get a better look. I fear that I will be learning a lot about how these engines are put together.

I paid 600 for mine. The sunroof leaks when it rains, has minor fender damage, has bits of rust on the body, and has a busted odometer at ~235k ... but it runs great and has been bullet proof. I saw one that was better looking with bad brakes and a questionable engine for 300 soon after that.

I would say ~1k would be a starting point.

I bought my quite functional (at the time :() 300D turbo with ~285k for 1600 and it was in pretty good cosmetic condition, aside from the paint.

A W123 for over ~2500 has to be in pretty good condition, given the market conditions, unless the seller is an asshat.

I would not buy a wagon without a visit to a mechanic, with specific attention given to the magical rear suspension. Wagon parts tend to be unique, unique is not what you seek in a car that will need work at some point; there were many more sedans made than there were wagons.

Driving a w123 diesel like a modern car will not have the results you seek. It is simply impossible to hit triple digits in these non turbo diesels without a hill involved. Likewise, the only thing you will beat off of a line is a bus or a truck; you stop missing acceleration after a while.

1977-1983 240d with manual climate control. ;)

With the 1981-1985 ACC, you might have to replace a monovalve or re-solder the ACC board to have it work perfectly. 1977-1980 ACC? Have a look at this. http://www.peachparts.com/Wikka/W123ACC1Conversion

The best year for the 240d is 1983 and 1985 for the 300d/300cd/300td. The later models have lower gear ratios for better highway travel and many other improvements. There's a clear difference between well-sorted 1977 and 1985 models in refinement and drivability. They're still bested by a Kia Rio in all aspects though.
Well yeah, the HVAC in my 79 240D is pretty awesome. I have thought about converting my 77 300D to it but had not looked into it, I am going to have to save that link. The added benefit is separate climate zones like a new car.

We are the original owner of a 77 300D and I bought an 85 300D earler this year. It honestly is night and day with what was done to the car over the 8 years of production.

I did a valve job (my first ever) on my 77 300D and now it will not start. When it does start, or tries to run I should say, it kills itself immediately; all while the car is shaking violently. Just went though it the 3rd time and the spacing is good.

Anyone have any suggestions?

Intake/Exhaust clearances could be mixed up if the diagram was read upside-down. .10mm exhaust and .30mm intake for nonturbos. You're measuring at the camshaft and rocker arm, right? Adjusted valves with the camshaft pointing straight up for each valve? Any binding linkage cutting fuel?
I mucked up one valve but noticed and corrected it once I went to the next one. After reading that switching the intake and exhaust clearances would result in not starting (on some forum somewhere) I went through and checked each one again, each at the 180 degree mark and at .1mm or .3mm. While I am sure that I did not gently caress up, what with checking a couple times now, I am sure I will check again tomorrow when the sun is out.

As for linkages, they are all moving freely and not touching the fuel lines inappropriately.

I got a 78 300d last summer and attempted to do a valve adjust on it myself. Did not turn out to well, though luckily my dad is a diesel mechanic and he helped me finish it up.
Valve adjustments are a bit tricky, I had never done one before and there is a lot of "feel" to get them right. Any chance you could get a hand from someone who has done a few valve adjusts before before?
I'd also suggest getting the correct tools as well, something like these: http://mercedessource.com/node/715
I heated and bent a old set of wrenches I found, and while they sort of worked, there is no substitute for the correct tool.
I'm no expert at all, but from the sound of it in the video, they have been adjusted too tight..? I'd suggest not starting it again and re-doing the adjustment. Like I said, it takes a bit of practice to get the feel for valve clearance right.
I bought a set of the Hazet wrenches for my birthday, so I have the right tools. Nothing beats breaking the family car, that we have owned since 1977 and was flown in from Germany, for my birthday :geno:.

I am going to talk to a couple people I know that work on cars and see what they say. From everything that I have read about valve adjustments, I have the spacing perfect but we shall see.

My 700 dollar 1979 240d has been a great car, though it tends to leak when it rains, the rear suspension is hosed, and there is epic blowby. All told, probably spent 500 (plus registration) to keep it going. It has been a super reliable car even though it has had some annoying issues.

If it is in perfect condition, that is the average going rate for a euro manual 300D.

So, I am thinking about getting a (4 speed, on the floor) 1966 W110 220D. The fuel timing is hosed, so it would be 1000 (listed, but likely lower with some talking) plus a trip to the mechanic.

How horrible of an idea is this? Considering I have never seen a W110 at the local wrecking yard, I suspect anything I ever need will not be pleasant.

I heart the eugenics in my driveway of only having W123 (77 300D, 79 240D, and an 85 300D I am going to sell) but this car looks pretty awesome.

I plan on going and seeing this tomorrow (the dude still has not sold it in ~4 months) but the asking price is now 600 instead of 1000. I really want it but I have to think objectively, it will take a minimum of ~1k to get on the road and then a couple grand to fix the glaring issues; besides the engine needing the injection pump timed to actually run, and hopefully that is all it will take, there is rust which would I would want dealt with asap and the interior is pretty hosed.

In other news, my 85 300D works again after I put it back together for the most part, with the help of starting fluid; seems the glow plugs are content with doing nothing useful. Once I finish bolting the exhaust back on, it will be taking a trip to the mechanic to fix the brakes; then my mother can work on destroying that car instead of the 77 300D I want to convert to manual.

How bad are W123's (most likely diesels) maintenance/parts wise?

Common issues seem to include anything to do with Vacuum (which is a lot of things) are there wiring/electrical issues?

I know that Mercedes automatics are great, are the manuals 4 or 5 speed (or what years had what) and do they have any electrical overdrive fuckery or whatnot.

What are the things that notoriously break and how much/how hard are they to fix, and finally, what mileage would a 240D see realistically? Is it worth bothering with diesel or are the 280's in the same ballpark of fuel consumption.
They are relatively common at picknpull, keeping them going is pretty reasonable. There are stupidly expensive components but I chalk that up to the price of german engineering. The heater coolant valve on my 77 300D failed, it is ~600 bucks and is a mixture of electricity, vacuum, and coolant; I bypassed it, instead of replacing it, with the thanks of a forum.

On the 240D, the vacuum nonsense is far less prevalent. The 300D has more, a lot more; the later the car the worse it is, the lines in the engine bay on my 85 are like double compared to my 77.

I would be hard pressed to purchase an automatic at this point. The vacuum nonsense impacts the auto, especially if it has that vacuum piece on the top of the engine. The manual 240D I have has nothing bizarre like you describe. 5 speed in a 123 is quite uncommon, from what I have seen.

My 240D runs around 30 mpg when I bother attempting to calculate it.

I went from an E39 528i touring that I loved, and an E46 325i sedan I hated, to W123 diesel Mercedes.

I enjoy driving as much, if not more, simply because the edge is relatively slow (~80mph) compared to the fun I had driving the BMWs (100+mph); captain slow reviewed a sluggish hatchback and provided a more eloquent description of this concept.

Also, gently caress computers in cars. So what if my vacuum locks don't work after being left to sit for an hour, at least a computer that costs thousands to replace is not involved with the basic function of the engine. :colbert:

The previous owner (from the previous cl post) cut a lot of corners. Painted but didn't fix dents or deal with rust and sunk money into a flowmaster, so it sets off car alarms, while the shift linkage has issues and brakes need attention. My 240D has more character for it's own good but it is relatively safe to drive, as opposed to that thing.

Hearing the price of door seals, however, was cringe worthy; ~800 bucks for the back 2 doors alone. Someone found an OEM set of all 4 in Germany for ~650 shipped, I sense I will be putting my faith in them.

Edit: I figured out the speedo being off is due to someone putting 175/70r13 on the car while the spare is 185/80r13 (the correct size). Looking at 185/80r13 (non trailer) tire prices on the internets makes me sad.

The window regulator was broken when I got my 300D stick, got around to dealing with that today. Mercedes wanted ~650 for the thing, I got a perfect one at pick n pull for 11.72 cents.


So, the alarm screaming when the car is off, the door is open, and the headlights are on; what causes that lovely tone on an early w123? I assume it is in one of the magical boxes that have one of the only integrated circuits on the car, sadly.

I heard my 79 240D do it 2 or 3 times in a couple years (the wiring was less than ideal on that thing, obviously) and I know I am going to gently caress up eventually on this 77 300D stick. I know the newer cars (~82+) have it, they also have entirely different circuitry and I don't want to mix and match too much.

I then found out the electric plastic backing on the glass is different than the manual one so I have glass from a wrecking yard and now need to figure out how to adhere it to the plastic from the manual assembly.

I had an E39 wagon, the injection computer failed and a mechanic was in complete shock that the transmission was still working; it was around either 150k or 200k I believe. gently caress computers and gently caress maintaining an early 2000s BMW.

The manual 1977 300D I purchased almost a year ago is a decent daily driver. It was ~2200 and I talked her down a couple hundred due to the syncros being trashed. I have spent about 2k since at the mechanic and a couple weekends here and there sorting out some issues. I am getting on an even keel with maintenance and expect to get the timing chain done soon. Admittedly, there is a gaping rust hole in the trunk behind the passenger wheel well, the cluster isn't lit and the fuel gauge is wrong due to some electrical gremlins, and the driver seat is on it's way out but things seem to be doing alright in the grand scheme of things. Hell, the cruise control almost works even.
