From the introduction: 

"The aim of this Manual is to help you get the best value from your vehicle. It can do so in two ways. First, it can help you decide what work must be done (even should you choose to get it done by a repair shop), provide information on routine maintenance and tune-up, and give a logical course of action and diagnosis when random faults occur. However, it is hoped that you will also use the book for a second and fuller purpose, that of tackling the work yourself. On the simpler jobs it may even be quicker than booking the vehicle into a repair shop and going there twice, to leave and collect it. Perhaps most important, much money can be saved by avoiding the costs a repair shop must charge to cover its labor and overhead.

The book has drawings and descriptions to show the function of the various components so that their layout can be understood. Then the tasks are described and photographed in a step-by-step sequence so that even a novice can do the work."
