|---|---|---|---|---|
| Licensed and SORN counts | Vehicle licensing statistics Department for Transport | End of March 2026 | 565 Mercedes-Benz 400 420 SL records (licensed and SORN) | 15 September 2026 |
- 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 2007.
- This version groups DVLA’s detailed model names “420 SL AUTO”. 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 most licensed at any year end since 1994, plus any first registered after that year. Other versions are those of the same model whose licensed count peaked in the same years, up to 2001.
