This is a customizable spiral notebook where you will put information regarding your vehicle. The purpose for this would be to keep track of things such as oil changes, repairs, accidents, tire rotations etc. Not only does it help you remember when things need to be done, but if you were to sell your vehicle, you have a journal of everything that has been done so that the person buying the vehicle has records of everything.
It is important to keep up to date with everything in the journal so that you do not forget something. There is a spot for note taking, so that for instance you can reference good mechanics or anything else that there is not a page for.
