- Figures cover Great Britain (England, Scotland and Wales). Northern Ireland is not included.
- Licensed counts are vehicles with a current tax or exemption at the end of each year (or the latest quarter). SORN counts are shown separately, from 2008.
- This version groups DVLA’s detailed model names “A4 AVANT S LINE TDI QTR”, “A4 AVANT S LINE FSI QTR A”, “A4 AVANT S LINE FSI QTR”. Engine size, gearbox, number of doors and fuel are ignored, so every engine and gearbox counts together.
- Survival compares the number still registered (licensed or SORN) with the number first registered since 2001. Other versions are those of the same model with the same average year of first registration.
- First registrations count vehicles registered in Great Britain for the first time, including used imports.
