Should I check the MOT history before buying a 1989 Jaguar Xjs He Auto?

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 1989 Jaguar Xjs He Auto?

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 1989 Jaguar Xjs He Auto?

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.

Do I need an HPI check when buying a 1989 Jaguar Xjs He Auto?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

1989 Jaguar Xjs He Auto

CarHunch analysed 531 real MOT records for the 1989 Jaguar Xjs He Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1989 Jaguar XJS is a deeply problematic proposition: just 20% pass the MOT first time compared to the UK average of 80%, and petrol variants achieve a 0% pass rate. While dangerous defects aren't showing in this data, the catastrophic failure rate reflects the age and complexity of these vehicles after 35+ years.

At an average mileage of 77,024, these cars have typically been driven moderately, yet they're still failing MOTs at an alarming rate—suggesting systemic issues beyond wear and tear. If you're considering one, budget heavily for pre-purchase inspection by a specialist Jaguar mechanic, because the statistics show this isn't a casual classic to own.
