Frequently asked questions

A mileage blocker is a device, usually hidden behind the dash or connected to the vehicle's wiring, that stops the car from recording some or all of the distance it travels. Unlike a one-off rollback, it can keep the odometer artificially low for months or years. Read more in our article What is a mileage blocker?.

Often, yes — but not always. Removal can leave physical evidence (trim damage, disturbed fasteners, spliced or taped wiring) and electronic evidence (mileage that disagrees between modules, gaps in recorded data, or wear that doesn't fit the number). We'll tell you how strong the evidence is either way.

A history report can only flag a rollback if a true, higher reading was recorded somewhere before it. A car that's had a blocker fitted since new, or whose records are thin, can show a perfectly clean report. That's why we include CARFAX as one input alongside physical and diagnostic checks.

For cars that have lived in the US, CARFAX has the most service and registration records to check against. If a vehicle has been imported or spent time abroad, we'll add a carVertical report on request.

Anywhere in the lower 48 states is covered by the standard fee. Alaska and Hawaii are available on request.

A photo-led written report, a clear verdict (Consistent, Inconclusive or Inconsistent), the CARFAX report, and a call to walk you through it.

No honest inspector can. Sophisticated tampering can be very difficult to detect and some vehicles retain little stored mileage data. What we guarantee is a thorough, independent, evidence-based inspection and a straight answer about what we found.
