Query: If I had this book when I started selling. . .

I couldn't find anything to read when I started selling cars 10 years ago. You fall down. You pick yourself up. That was my training. Now, I dont know if any one way to learn is better than the other. I wouldn't want to risk it if I were new. This book spells the sale out clearly.
