I picked up this book because I had heard good things about the series and because this particular book had "Speedy Motors" in the title. :)

It was nothing special to me. I thought it was a reasonably enjoyable easy read, but I cannot say that I would really recommend it to anyone. There are much better books out there. (My tepid evaluation is not shared by the many other fans of this series, so perhaps the book will work better for you.)
