It will be the best $12.00 you ever spent.
The next step is the CD that is the factory service manual. But, its no fun to navigate through.
You can also get the hard copy of the factory service manuals on e-bay. They are pricey ($50-$100) and you have to be patient.
There are several different factory manuals including engine, chassis, electrical, and climate control.
