The Topic is good, however the "book" is extremely disappointing. First, it states here that the book is paperback. I guess in the strictest sense that is true... however I was quite taken back when I ordered it here from Amazon.com - and received about 70 Xeroxed pages stapled together. Hardly what I expected for a "paperback". Getting past that, the material although relavent, is extremely outdated. If you want to build a high-end golf cart this might help. But if you want to delve into something modern (circa 2007) you won't find it here. I'm sorry to sound so harse but it is the truth. I'm also sorry to say: Shame on Amazon... you shouldn't advertise this as a "paperback" when you're really selling what amounts to a handful of photocopied pages.
