Jason,
You are doing a fine job. The only thing I would suggest is that on the summary listing, under Model, include the year, transmission type, body style, the number of passengers and EPA estimated MPG.

For Example:

2004 Toyota Prius HSD
CVT, 5 dr, 5 pass
61 City, 51 Hwy

or

2004 Honda Insight
Manual, 3 dr, 2 pass
60 City, 66 Hwy

This way, you can compare apples to apples and have some idea how the car is performing with respect to EPA estimates. If someone sees 106 MPG, but a 66 MPG estimate, they will probably at least question the data. Right now they have no reason to question anything. After all, it is the "REAL MILEAGE" database. From the name it sounds like someone went through the trouble of verifying the data.
