Jaguar Xjr (2004)
2004 Jaguar Xjr
CarHunch analysed 278 real MOT records for the 2004 Jaguar Xjr. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 Jaguar XJR's 78.6% first-time pass rate sits just below the UK average of 80%, which is respectable for a 20-year-old performance saloon, but the critical concern is that 42.8% of these cars have recorded dangerous defects—nearly double the typical rate—making pre-purchase inspection from a Jaguar specialist absolutely essential. With an average of 4.09 failures and 22.6 advisories per test, these cars demand consistent maintenance; the median mileage of 80,093 is reasonable for the age, but the high advisory count suggests accumulated wear across multiple systems rather than a single weak point.
Any buyer should treat this XJR as a high-maintenance classic that will reward diligent ownership but punish neglect. Insist on a full history check focused on suspension geometry, cooling system integrity, and brake condition—the advisory frequency hints that these are the problem areas—and budget for regular specialist servicing from day one.
What to check before buying a 2004 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.
- ⚠️ 42.8% 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.
