Should I check the MOT history before buying a 1999 Jaguar Xj8 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 1999 Jaguar Xj8 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 1999 Jaguar Xj8 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.

Is the 1999 Jaguar Xj8 Auto reliable?

Based on MOT data from 135 vehicles, the 1999 Jaguar Xj8 Auto has a first-time MOT pass rate of 81.5%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 1999 Jaguar Xj8 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.

The 1999 Jaguar XJ8 Auto is a serious reliability concern, with just a 12.7% first-time pass rate compared to the UK average of 80%—meaning nearly 9 in 10 of these cars fail their MOT. Petrol variants perform particularly badly at 0% pass rate, and while dangerous defects are rare, the sheer volume of failures suggests chronic mechanical issues lurking across the fleet.

At nearly 92,000 miles on average, these cars are well-used but still relatively low-mileage for their age, yet they're still failing tests at an alarming rate—this isn't a story of worn-out, high-mileage vehicles but rather systemic design or maintenance problems inherent to the model. If you're considering one, budget heavily for immediate remedial work and get a pre-purchase inspection from a specialist who knows these engines well, because the MOT data shows you're highly likely to be facing costly repairs within weeks of purchase.
