Limitations
- Figures are raw counts. VerifyTheVehicle holds no vehicle sales or registration data, so nothing here is normalised into a rate — a high-volume nameplate will tend to show more of everything.
- Coverage is limited to the 37 makes and model years 2015–2025 currently in the index, not the entire US fleet.
