Risk Profile by Mileage
How mechanical risk and MOT failure probabilities escalate across odometer milestones for the Toyota Corolla.
Pristine mechanical zone. Negligible MOT failure probability outside of tyre punctures.
First MOT inspection threshold. Front brake pads and tyre wear are standard items.
Suspension bushes, anti-roll bar links, and auxiliary drive belts enter wear cycles.
Emissions equipment (DPF/catalytic converters), suspension shocks, and cooling components require verification.
