What do six years of MOTs show about owning a Jaguar XJS?

Of failed Jaguar XJS MOTs, 19.3% were retested the same day and a further 67.4% within 10 days; the median failed car passed its retest after 4 days (2019–2024, n = 2,844).

If a Jaguar XJS fails, does it fail again?

23.1% of Jaguar XJS models that failed an MOT failed the next one too, against 17.3% after a pass (2019–2024, n = 1,470). The failure most likely to come back is ‘lamps, reflectors and electrical equipment’: 25.8% of those fails recurred at the next MOT.

Jaguar XJS MOT: quick answers

What is the Jaguar XJS first-time MOT pass rate?

79.5% of first attempts passed in 2024 (3,075 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.

Why does this number differ from other sites?

Other sites may count retests or all attempts. This page uses 3,075 primary tests: 20.46% failed first time and 82.2% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 59.1 is shown separately.
