How to compare two used cars beyond price and mileage
By Plateworthy · Updated · Editorial policy
Compare the unanswered questions as well as the asking prices. A cheaper car with unverified repair work is not the same proposition as a car whose history and maintenance you can explain.
Use the same evidence categories
For each car, record asking price, identity checks, current MOT status, usable mileage readings, service evidence and any recorded finance, write-off or theft result. Keep the retrieval dates so you know whether you are comparing equally recent checks.
Use ‘unknown’ for missing evidence rather than zero faults. An empty field should not make one car look better than an alternative with a documented issue and a documented repair.
List the work needed before relying on the car
Request appropriate inspection and maintenance quotations for the actual findings. Add insurance quotes and the practical costs relevant to your use. Do not estimate repair bills from a category or short MOT comment alone.
For a recorded write-off or auction history, compare the repair file and inspection scope. A lower price only becomes a clear trade-off when you understand what evidence and work accompany it.
Choose the next action, not just a winner
List the one unresolved question most likely to change your decision for each car. Ask the seller for that evidence before spending more time or money. A useful shortlist can rule out a car or justify an inspection without pretending to predict every future fault.
Plateworthy account holders can compare two or three purchased reports side by side. The comparison preserves the recorded evidence; it does not replace current condition checks or turn an unknown status into a clean result.
Common questions
- How should I compare two history reports?
- Compare the individual recorded findings, missing evidence and retrieval dates alongside service records and inspections. Plateworthy does not assign a vehicle score or predict future reliability.
