CarHunch analysed 5,344 real MOT records for the 1997 Jaguar Xj. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1997 Jaguar XJ's 75% first-time pass rate trails the UK average by 5 percentage points, and a concerning 21.3% of these cars have recorded dangerous defects—a red flag suggesting systemic issues with brakes, steering, or structural integrity that demand pre-purchase inspection. This is a car that will need proper vetting before you commit.

At 103,000 miles median, these XJs are well-used but not excessive for their age, yet they're averaging 3.16 failures and nearly 20 advisories per test—that's significantly more than typical for a saloon of this generation. Before buying, get an independent pre-purchase inspection focused on suspension, cooling system, and electrical gremlins; these luxury cars can become money pits fast once warranty is gone.

What to check before buying a 1997 Jaguar Xj

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.
  • ⚠️ 21.4% 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.
