Jaguar Xjr (1999)
1999 Jaguar Xjr
CarHunch analysed 475 real MOT records for the 1999 Jaguar Xjr. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1999 Jaguar XJR falls slightly below the UK average with a 76.5% first-time pass rate, but the real concern is that nearly a quarter of these cars (23.4%) have recorded dangerous defects during MOT testing — well above the typical threshold for buyer caution. This is a temperamental machine that demands serious pre-purchase inspection.
These XJRs are averaging just under 93,000 miles for their age, which is typical, but they're racking up an alarming 3.36 failures per test and 20.9 advisories, suggesting chronic wear across multiple systems rather than isolated problems. Before buying one, get a pre-purchase inspection from a Jaguar specialist who can assess the supercharger, cooling system, and electrical gremlins that plague this generation — don't rely on a passing MOT to tell you the full story.
What to check before buying a 1999 Jaguar Xjr
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 23.4% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
