Luxury supercar marque Ferrari has admitted it was aware of dealers using a device that allowed technicians to reset the mileage on used cars. A former salesman for the brand, Bud Root, filed a legal case against the Italian manufacturer last year, claiming he was fired for whistleblowing on the practice.

A device known as a 'DEIS tester' was used to roll vehicle odometers back, allowing used vehicles to be sold for extremely high prices. Root alleges that this practice only took place with the express permission of Ferrari head office, casting doubt on the mileage of the brand's used cars.
