Average for cars of the same age and mileage
Top failures
Position lamp not working 7.66%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Engine warning light inoperative or lit 4.8%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Coil spring fractured or broken 3.82%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Wiper blade not clearing windscreen 3.21%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp beam pattern obviously incorrect 2.93%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
CV joint boot split or insecure 2.58%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Common advisories
Tyre worn close to legal limit (12.59%) · Brake disc pitted or scored (11.92%) · Headlamp lens has a coating (9.89%) · Brake pipes corroded and greasy (9.83%) · Number plate lettering deteriorating (9.32%) · Coil spring showing some corrosion (9.22%)
