Attached is an Excel spread sheet I use to manage the cost of ownership of my Prius. I use it to compare my savings over my previous car (Audi A4). There are two pages to the book, the first tracks milage and expected service dates, and the second page keeps track of the overall cost of ownership. This is a work in progress, so please feel free to use it and comment.

Enjoy.
