Should I check the MOT history before buying a 2005 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 2005 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 2005 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 2005 Jaguar XJ passes MOT at almost exactly the UK average of 80.2%, which is respectable for a 19-year-old luxury car—but a significant concern emerges in the dangerous defects data: nearly 40% of these vehicles have recorded a serious safety issue at some point, well above the typical threshold, making pre-purchase inspection non-negotiable. Petrol and diesel variants perform comparably (80.5% and 78.9% pass rates respectively), so fuel type isn't a deciding factor here.

At 75,000 miles median mileage, these XJs show typical wear for their age, but the real story lies in the failure pattern: owners face an average of four failures per test alongside nearly 23 advisories, pointing to cumulative wear across multiple systems rather than one dominant weakness. Before committing to one, pay a specialist £150–200 to inspect the suspension, cooling system, and electrical architecture—these older Jaguars are complex and expensive to repair when neglected.

The 2005 Jaguar Xj has a decent first-time pass rate (80.2%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 22.9 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,682 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
