They are out there. They aren’t cheap. They are illegal because they can be used to change the odometer reading. You are better off getting caught for murder than rolling back car mileages.

You wouldn't necessarily roll back the odometer mileage, although I can see how that would be an obvious option of such a device. I'm just talking about something that could stand in for the true mileage register when some gestapo agent comes looking to tax your driving. When you sold the car, you'd remove it and the true mileage would register.

At least if you were honest with the buyer. There's nothing whatsoever wrong with screwing the government, in my book, but a private party is another story.
