- This covers cars tested in Guildford (DVSA's postcode_area field is the testing station's location, not the vehicle owner's home address).
- The age-adjusted figure is standardised to the national vehicle-age mix, so it isn't just reflecting whether this area's tested fleet happens to run older or newer than average.
