Car Buying Guide

Hi everyone. My partner and I are preparing to release a car buying guide and I wanted to post it here for review
by the members. The guide outlines information you should know when looking to buy a car. We are looking to
eventually sell the guide but would like to offer it free here to the members in exchange for your feedback.
If you can, please review the guide and provide feedback on what you think of it. What do you think of the content?
Any information you feel it is missing? What, if anything, would you be willing to pay for such a guide?
You can preview the guide here: http://www.my-auto-loan.info/buyacar.pdf
Please provide feedback as you can. Thanks.
