Example report
2017 Volkswagen Golf 1.4 TSI
62
High risk
Mileage is high for age and the model has a known timing-chain concern.
Advert mileage matches the latest MOT record.
Transparent by design
This is a first-pass sense check, not a mechanical inspection or a full finance and write-off history report. The useful bit is knowing exactly where each warning comes from.

Words worth questioning
Used Car Check recognises hundreds of common phrases and turns them into specific questions you can ask before committing to a journey.
“Easy fix”
If it is genuinely easy and cheap, ask why the seller has not fixed it.
“Sold as seen”
A phrase worth understanding before you assume it removes all of your rights.
“Just needs a sensor”
Ask for the diagnostic code and evidence behind that diagnosis before travelling.
