300

The “300” designation graced Mercedes-Benz models since 1951, and you can find it on everything from roadsters to sedans. Although the number alone doesn't reveal much, one thing is for sure; it's an inline six. Moreover, they are almost all indestructible, but considering that even the last ones are close to 30 years old now, investing in a service manual is always a good idea.

Indeed, repair manuals contain everything you need to keep your Merc on the road, including troubleshooting and repair procedures, step-by-step instructions, torque specs, and wiring diagrams.

And, of course, we have model-specific manuals for pretty much any “300” model ever made. For instance, if you have a pre-2000 diesel S-Class, look for a Mercedes-Benz 300sd repair manual. For a 3.0 diesel W123, get a Mercedes-Benz 300d repair manual instead, and so on.

No matter the Mercedes-Benz model you are working on, we’ve got you covered!
