W123 Diesel values?

Hi Folks. Would anyone be kind enough to give me idea of what money a late W123 300D is bringing these days? Regards Corrado

in the last year or so, the diesels have been getting a bit more difficult to find for sale.

You could get a rusty one without rego for about 500 to 1k depending on year/options and whether ti's a running car.

with rego and in a coupe or wagon with manual transimission, and very little rust can be 10k+ or even more with the right colour and options list with little KM's

To me, the ultimate combination is

Post 1981 for upgraded glow plugs and 8HP more from factory
Coupe' 2 door
5 speed manual transmission
Factory garret turbo Diesel engine ( there are after market turbo jobs which aren't as good as the block doesn't have oil squirters under the pistons to cool them )
Electric windows
manual sunroof
Tachometer on the dash
"economy gauge" on dash, which is converted to be a turbo boost gauge.

Thanks for the response. Yes diesels do seem to be rare these days. Thus I have one in mind so I'll be more specific. A friend actually has a 1984 300D in white, auto, 300,000 plus on the clock and country car from new. The body appears to have very minimal rust but the only catch really is that it has been off the road for about ten years. In that time it's only been driven three times to move it to another property to be stored outdoors.

Change all rubber hoses, lines and seals as you find them leaking due to age hardening and cracking.


Also, love the username :P I have a diesel coupe 85 w123


Check rust and functionality of all things in the car.


Change the oil, fuel and all filters before you start the engine


Put some liquid directly into the cylinders ( throw glow plug holes ) and turn the engine over by hand ( 27mm deep socket, from under the car with breaker bar/ ratchet, no need to remove fan ect: ) with the glow plugs removed ( to stop compression building ) to lubricate the engine nicely before you even attempt to start it. ( replace glow plugs when ready to start the engine )

I cannot give a rough estimation on price without going over the car top to bottom. Price is really indicated by how much money and elbow grease is needed to be put into the car.

The sedans range from $2.5K upwards on Gumtree / Carsales. Given it has sat around for 10 years, the biggest determinant of value is level of rust. Being in Vic, the RWC will be rejected based on there being any ....

Math's advise re starting then engine is spot on. Also, budget for a complete overhaul of brakes as the lines will etc swell and fluid needs bleeding. Battery, new coolant, water pump is probably shot (not too dear to replace) and new trans fluid + filter. So it will need a lot of work to bring up to speed. If you can do yourself, then all good but if you are paying a mechanic, it will quickly mount.

I was generously given a 300D sedan but invested significant time myself to bring it up to scratch. This did include a full respray.

So ... Assuming rust free and the paint will buff up OK (so no panel beating required) and the interior is fine I wouldn't pay much more than $1K.

Math - Has this been done ? I have a few economy guages and would love to convert the vacuum measure to boost pressure measure.

yes it has, and it's fairly easy to do :)

It will show 0 to 10psi boost :)

Happy to help :)

I would put a boost gauge on first and drive around and check the engine is making full boost. ( 10psi in my case)

Then, i would do the mod, as 11 o'clock position might not be the right one. When i followed the instructions 10psi was the middle of the gauge, so it was more 9 o'clock.

so yeah, make sure it's boosting properly so you get it working accurately :)

Thanks for the info, at least I know what I'm getting myself into. Though I will most likely pay over market value given it's a mate who is selling it and I don't want to beat him down too much!lol
