This book is about selling cars, not ANYTHING. Also, it's not very good about that. It's extremely outdated; things have changed so much since JG was on top that at some points reading this book is like a history lesson.Also, the info, with a few exceptions is vague filler. I would have rather paid a buck for a 20 page book, which was all that was needed.The funny thing is that the title sold me, so I guess he was doing something right there.
