This is pretty cool. I’ve been saying for years that all cars should come standard with a big readout that says how much gas you’ve spent (and how much money that translates to) for every trip you take. I’m a big data-nut, so I may get one of these, or a ScanGauge II some day. The only thing I could think that would make these better would be a USB port to dump the data off to my computer so I can archive and visualize it.
