When it starts failing

At 60–80k miles this one fails 17% of its inspections, about what an ordinary car of the same age does.

221 British inspections, grouped by the odometer reading recorded at the test.

Half of these have more than 40k miles on them. That is how far people drive this car, not how long it lasts.
