From Wikipedia: The Haynes Owner's Workshop Manuals (commonly known as simply Haynes Manuals) are a series of practical manuals from the Haynes Publishing Group aimed at both DIY enthusiasts and professional garage mechanics. The series primarily focuses upon the maintenance and repair of automotive vehicles, covering a wide range of makes and models (300 models of car and 130 models of motorcycle), but it also includes manuals in the same style for domestic appliances and personal computers, digital photography and model railways, men and babies, sex, and women. The last four were made slightly tongue in cheek, but have proved very popular.
This book was a great help in working on a 1962 Baja bug though it does not contain information on some of the more important things that need to be fixed in the car. The book is great for most things in a general context but when it comes to specific information it is missing some very important things.
