2014 Mercedes-Benz SL MOT pass rate and common faults
MOT tests in 2025, published 22 Jun 2026. DVSA publishes a new year each summer.
1,077 Mercedes-Benz SL cars first used in 2014 had an MOT in 2025, at about 11 years old, and 85.5% passed first time. That is above the 68.6% for all cars first used in 2014.
The year is when the car was first used, as on its V5C log book, not the model year.

Typical mileage
Recorded mileage at the MOT. A car well above this range has done more work than most; one far below is worth a closer look at its MOT history.
| Cars | Low | Typical | High |
|---|---|---|---|
| 1,077 | 33,700 | 46,700 miles | 63,600 |
