Press and data
Plateop analyses open vehicle inspection data for car buyers. We share the resulting figures here with journalists and researchers: free to use, with attribution.
The APK monitor
The APK monitor is a monthly publication on the state of the Dutch vehicle fleet, based on open inspection data from the Dutch vehicle register (kentekenregister). Each edition shows how many inspections resulted in at least one failure item, broken down by vehicle age, which defect categories occur most often and which models stand out in either direction.
An edition appears monthly and is never changed after publication: cited figures remain verifiable on this page.

The European Inspection Index
The European Inspection Index puts the inspection figures from the Netherlands, the United Kingdom and Czechia side by side: not as a raw percentage, since those countries each count failures differently, but as an index relative to their own country average. One hundred is average; higher means failed more often than average in that country and age group.
View the Inspection IndexMethod in brief
All figures come from open inspection data in the Dutch vehicle register over a rolling three-year window. Only genuine failure items count; advisory items are excluded. Fleet figures come from a broad, representative sample across all age groups; category and model figures come from the models Plateop tracks. Each edition states its exact coverage, observation window and thresholds.
Citing
