Particularly with company/fleet trucks or cars, you normally have an "own" paper log with all the repairs and maintenance performed, so, if you are in good faith, if the odometer breaks at (say) 190,000 miles and the new one reads 110,000, you can easily prove that the vehicle is at 300,000.

When you sell that vehicle only stating "odometer reads 110,000" you are inducing the buyer into error (lying by omission, and you are in bad faith as you have the documents that reveal the real mileage).

For those rare cases where there is no such documentation there is usually the formula "mileage unknown" or similar, but usually it draws the price down to the minimum.
