The first part of the book is step by step instructions on converting a vehicle from scratch. It would be very interesting to know if anyone who ever read this book followed it step by step and converted a vehicle using it. All sorts of templates, electronic diagrams, and parts lists. The middle of the book has a lot of equations in it. I found the last part of the book to be the most interesting for myself. It chronicles the electric car phenomenon of the 1970's leading into the 1980's. A lot of interesting historical photographs in it. With so many off the shelf parts available today, it's easier then ever to make an electric vehicle. Things have came a long way since this book was written. This book will really make you appreciate the parts available today.
