Digging into the data to learn which cars are kept the longest can reveal something interesting about what’s on our nation’s roads. Previous lists from iSeeCars.com had some fairly predictably winners. That was until this year’s data was revealed.

Folks in the market for a fuel-efficient and reliable commuter car can likely pick up a Prius for cheap and still get plenty of life out of it, even with a battery that has seen some age and mileage.
