The number is entered by whoever benefits
An owner recording their own mileage before a sale has an obvious interest. The problem is structural, not moral.
WHY THE RECORD FAILS
It is authored by the party who profits from it.
Owners maintain the service book. Owners sell the car. Improving one's own record requires no forgery skills and no accomplice.
Paper stamps are trivially reproduced
A service booklet is a printed artefact. Nothing about it resists a determined seller with a rubber stamp.
Honest sellers cannot prove it
A genuinely well-maintained car looks identical to a badly maintained one with a good story, so the honest seller gets the same discount.
So the market prices for the worst case
Every buyer pays a margin for the possibility of deception, which is a tax on the people who were telling the truth.
If you buy, sell, or service used cars.
Being designed and nothing to use. The useful thing is concrete: what you check today, and what you have been caught by.
