I borrowed a slew of car care books from the library to judge which one I'd like to own. This one by far has the best diagrams. They have enough detail to recognize the parts for what they actually are without being too complicated. I'll probably copy some of the pages to keep as reference. However, the subject matter of the book isn't as detailed as i wanted it to be. The writing of the book is pretty detailed, yet not complicated as some of the other books were. However, since it wasn't as detailed as a couple of books i read before this one, I actually didn't really read much of it. I just skimmed it hoping to gain new information, but no such luck. If you want a quick read for very basic car care, this may be the book for you.
