2000 Jaguar XK — MOT failures & pass rate
The 2000 Jaguar XK passed 77.1% of its 3,186 recorded MOT tests. Coupes & convertibles of a similar age fail at 22.3%, so the 2000 XK sits squarely on the average. Failures cluster in suspension, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — suspension (8.7%) and lighting & signalling (8.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, component mounting prescribed areas and headlamp aim — catalyst emissions alone was recorded 354 times.
Mileage is the strongest signal on the record: 10.9% of 0-30k cars fail, rising to 32.1% once past 150k — 2.9× the risk.
Advisories point at the next bill rather than this one: suspension was flagged on 29.3% of tests without failing them.
The trend is improving — the fail rate fell from 23.3% in 2021 to 21.1% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 29.3% | 933 |
| 2 | Brakes | 22.1% | 703 |
| 3 | Tyres | 20.4% | 649 |
| 4 | Body, structure & corrosion | 11.5% | 366 |
| 5 | Other defects | 8.4% | 268 |
| 6 | Emissions & environmental | 7.8% | 249 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 147 | 10.9% |
| 30-60k | 595 | 16.1% |
| 60-90k | 1,131 | 23.1% |
| 90-120k | 839 | 24.8% |
| 120-150k | 359 | 30.6% |
| 150k+ | 106 | 32.1% |

What to check before buying a 2000 XK
On a 2000 XK, suspension is what the MOT record says goes wrong most — it appeared in 8.7% of tests. Check these areas before you commit.
- Suspension (8.7% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Lighting & signalling (8.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (8.1% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
