Buy a used car with your eyes open
Know the mileage before you trust it.
odotrace decodes any VIN and cross-checks official odometer readings for signs of a rollback — free, built on government data, with the source of every figure shown in plain sight.
No VIN handy? Try the decoder with a European VIN or a US VIN.
What makes it honest
Free official sources only
UK DVSA MOT history and the Dutch RDW’s own odometer verdict — read from public APIs at the moment you ask. No scraping, no resold data.
Provenance on every figure
Each reading shows its source, its date, and whether the odometer was actually read. Numbers you can trace, not a single green tick.
Gaps shown, not hidden
Where no official record exists, we say so. A rollback is flagged only on a real drop between two readings — never guessed.
Typical mileage by model
Before you trust an odometer, know what is normal. Each page shows the typical mileage range — 10th percentile, median, 90th percentile, in km and miles — for a model and year, computed from real UK MOT readings. 23 models · 90 year pages · source: DVSA, OGL v3.0.
