1984 Mercedes-Benz W123 300TD 3.0L turbo diesel from North America


It's not slow. It's stately.


At purchase:

A/C inoperative.

Sunroof inoperative.

Passenger front window inoperative.

Driver's rear window inoperative.

Wear/small tear in driver's seat leather.

Some rust and paint fading (Florida beachside car).

Since purchase:

Climate control panel broken (heat - A/C-blower).

Fuel filters replaced/fuel lines cleared.

Front brake pads/rotors.

General Comments:

Built and drives like the tank it is. Bulletproof mechanically (with proper maintenance). Roomy, comfortable, well appointed interior.

It's not the fastest car on the road, but it will get you where you want to go and back every single time.

I drive this car daily around town, and make several highway trips a year of about 400 miles each, averaging 29 mpg (not bad at all for a car that is heavier than most trucks).

This car has only stranded me once, right after I purchased the car (due to blocked fuel filters, previous owner was somewhat lax about maintenance). Working on the non-running problems now. Parts are plentiful, easy to get and relatively inexpensive.

For $1300, an excellent purchase. I intend to drive this car to the grave - either its or mine.

The best car I ever owned


Nothing, awesome car after many years, even the AC blows cold,

General Comments:

Like, I said this car is the most amazing car I ever owned. If you want to go fast, definitely this car is not for you, but if you want a car with class, easy to maintain, and an average of 27mpg, then consider this great German machine.

I totally agree!

Its quality, for its age and condition, it is in great shape!

My previous car was a Opel Corsa 160 that was not quality. Its looks were deceiving, and it cost a lot and was sold at a huge loss.

Now after 13 months of driving my land yacht, I have never been happier.

Mercedes rule.

I bought my Benz W123 three months back. While washing under the body, I found a little corrosion, hence I put it into the workshop to do the painting. How long can I keep the car without getting corrosion, and advise me what action that I have to take to prevent corrosion happening again?

MB doesn't make them like this anymore!


I bought a neglected car, therefore my comments are somewhat not typical of the other posters who say this is the most solid car built.

That said, this is a very sturdy car, but has needed a lot of TLC to bring it back to its former glory.

Since owning it, I've replaced all fuel lines, fuel pump, oil cooler lines (PITA), left ball joint, tie rods, valve adjustment, alignment, brakes, repacked front bearings, exhaust clamps, new antenna, corrected faulty wiring from PO's poor attempt at stereo installation and changed all belts.

I still need to flush out the cooling system, which is filled with rust, and put in Mercedes coolant, change the transmission cooling lines and put in a rebuilt steering box.

Cosmetically, the car also needs some help as the driver's fender is dented and could use paint. I did install euro lights, which helped the appearance some, but overall, it needs a bit more help.

General Comments:

Good car, but not exactly cheap to maintain. I do all my work myself, but sometimes I don't have enough time.

The vacuum system in these cars is quirky and affects the transmission shifting, which was horrid when I got the car.

After a lot of tweaking / adjusting, I've got it to where it is somewhat civilized, but still needs the Midas touch from a trained MB tech. I may bite the bullet and have a MB Indy put some final touches on the transmission adjusting.

Next year, I'm planning on replacing the timing chain & tensioner. Hopefully after that, this car will be as good as new, and provide me with years to service.

I love the diesel engine, and hope to keep this MB for a long time. I also have a 84 300SD and a 86 300SDL, which was crashed and totaled (sadly).
