This manual is a consistent with others in this series. For [...], it is better than not having any information ... but not much better. Most of the procedures are sketchy at best, they will get an inexperienced mechanic into trouble quickly by omitting key steps in repair procedures. In many parts of the book, you will read "due ot the complexity of [fill in part or system here] ... this should not be undertaken by the home mechanic." They then proceed to omit the important information and provide you with generic procedures. Save your pennies and invest in the official Mercedes-Benz manaul.
