I was very disappointed with this book. It was severely lacking in information and seemed inaccurate as far as values. For example, I checked for the current market value of my turbodiesel Dodge Ram, but it wasn't even in there! It only had the base Rams, and the closest to my truck I could find was valued at half of what Blue Book values my truck as. The additional options is often not listed, and that is what gives the accurate values of a vehicle. Very limited, innaccurate information. You do better just going to kbb.com.
