Should I check the MOT history before buying a 2020 Jaguar Xj?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2020 Jaguar Xj?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2020 Jaguar Xj?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2020 Jaguar XJ is significantly more reliable than the UK average, with a 92.3% first-time MOT pass rate compared to 80% nationally—this is genuinely impressive. The dangerous defect rate of 8.6% is well below the threshold for concern, suggesting these are well-engineered cars with few critical safety issues.

At just under 30,000 miles on average, this cohort is running light for a four-year-old car, which partly explains the strong pass rate. With only 0.25 failures and 2.5 advisories per vehicle, these Jaguars demand minimal repair work, though the median CarhunchScore of 50 suggests you should still factor in depreciation and running costs before committing; budget for a pre-purchase inspection to verify service history and check for any suspension or electrical gremlins.

We have limited data for the 2020 Jaguar Xj — treat the figures below as indicative rather than definitive.
