(Sarah)A couple in California who ran a used car dealership embody consumers’ worst fears about buying used cars. They now face almost 80 criminal charges of grand theft by false pretenses, perjury, filing false documents with the DMV, and twenty counts of unlawfully rolling back a car odometer. The investigation started in April of this year, when a customer of the used car dealership brought her car to a mechanic with a functioning brain, who noticed that the car appeared to have traveled at least twice as many miles as the odometer indicated. Department of Motor Vehicles investigators looked into cars that the dealership had sold in the past, noticing discrepancies between auction records for those cars and the current odometer readings. Wait, though: how do you roll back an odometer when most cars have digital displays now?
