2001 Jaguar XJ MOT pass rate: 77.8% (1,643 tests)
Is the 2001 XJ getting worse?
Pass rate of 2001-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 78.5% +12.6 vs same-age |
|
| 2024 | 76.3% +9.9 vs same-age |
|
| 2025 | 78.5% +10.7 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

What mileage is too high for a 2001 XJ?
