Odometer rollback is illegal. According to the DMV, it’s done by changing or altering the mileage readings on a vehicle to make it appear to have a lower total mileage. Often, this results in the customer paying thousands of dollars more than the vehicle is actually worth.

Officials say if you’re in the market for a used car this holiday season, do some research before you buy.
