Oh,[:o)]

I have TWO super diesels in that case! An SDL and SD(the W126 model which precedes the W140).

I thought you meant a diesel with a SC hooked onto the PV belt.

300SDL (OM603.960)

Boge Turbo rear shocks(pretty easy to replace). Needed them 20K miles ago.

Changed tires twice. First time BF Goodrich Advantage Plus(treadwear: 520), second time Continental Touring(treadwear 560)(both have high treadwear ratings with M+S. Both are $50 tires that seem as good as Michelins.

Brake jobs had to be done. Replaced brake fluid a (every couple of years), changed front and rear rotors(10K miles ago) and brakes are changed at regular intervals(every 30K).

Fuel filters haven't needed to be changed yet. No algae buildup(which happens when water molecules are present in the diesel). Cheap and easy.

Replaced/cleaned the air filter every 15K miles. Cheap and easy.

Radiator had a plastic neck which broke off last summer. Fortunately I have a watchful eye, and I caught the coolant sensor light flashing on. I watched the temp gauge and it was rising quickly. Had to replace the radiator which wasn't that cheap. But I should never have to do that again. New radiator has a steel reinforcement, meaning it won't break.

The torsion bar which broke on mine(due to roadsalt) has no relevance to the 300D since the 300D has a torsion bar that would be a cake to fix anyway. They're cheap $$ too.

I have never had to replace a glowplug yet. But they are not very easy to get too(quite a dig).

I think that's it. In 4 years and 50K miles other than regular dyno oil changes(8 quarts to refill).
Honestly, that's ALL the maintenence that had to be done.

My sister has only had the 300D for one year. So far, all she had to do was have the brakes done once. Just the pads. It's been 35K miles so far with her 300D. Her 300D needs a good Italian tuneup, as it seems to be loaded with carbon. Everytime I'm over visiting, its the first thing I do.

W124 expenses are a little cheaper than W126 expenses. Specifically when it comes to brakes, and tire wear(lighter cars). The maintanence I listed was for my 1810 kg unloaded S-Class 300SDL.
