Even with the dawn on the digital odometer, used car buyers should be aware of odometer fraud. That's the warning from Carfax.
"In fact these digital odometers can be easier to rollback because A) we're not looking for it and B), there's widespread availability of tools that simply plug into the car's computer and essentially hacking it," said Chris Basso of Carfax.
Basso suggests checking with a site like Carfax or having an auto mechanic check out the car you're considering before you purchase.
