This numbers spreadsheet keeps track of most performance and cost metrics an anal user like myself might want to track for their vehicle(s). The vehicle image behind the MPG graph is easily changed by the user to an image of their own vehicle. I find the MPG by Octane and MPG by % Highway very interesting graphs. I’ve been playing with this since 2004 and have to wonder why I’m so anal about tracking this. It’s the nerdiness in my blood I guess. I was an IT guy for most of my career. In the actual template file, I have removed all but one row of data so the graphs will not show much of anything until some data gets populated but this is what it looks like after regularly populating data. Several of my friends like and use this and so I thought other Numbers users might as well.
