1999 JAGUAR XK84.0L Petrol

The vehicle’s most recent MOT test, conducted on October 15, 2025 , confirms it passed without recorded defects at 107,776 miles , though the preceding tests reveal an inconsistent pattern. The car failed twice in quick succession— May 6, 2025 and August 2, 2024 —despite minimal mileage progression (just 43 miles between failures in 2025 and 221 miles between the 2024 and 2023 tests). This suggests either intermittent mechanical issues not captured in the defect logs or a tester’s failure to flag critical faults during those failures. The July 6, 2023 failure at 106,783 miles —just three days before passing at 106,786 miles —implies a possible administrative oversight rather than a resolved mechanical trend. Without explicit defect details, the record does not provide clarity on whether structural or safety-critical components were repeatedly at risk. The recorded mileage of 107,776 miles over 27 years equates to an average of 3,992 miles per year , which is unusually low for a vehicle of this age and class. This suggests prolonged periods of inactivity, which can accelerate deterioration in suspension components, brake systems, and fuel systems due to stagnant fluids and seals. The 10-month gap between the 2024 and 2025 tests (August to May) aligns with the MOT cycle, but the three-day turnaround in July 2023 is anomalous and may indicate either a rushed retest or a vehicle that was briefly driven into compliance. Buyers should scrutinise whether this low mileage reflects genuine underuse or selective driving to avoid wear, as prolonged storage can mask deeper issues like seized suspension bushes or corroded exhaust joints. Given the lack of defect specifics in the MOT history, a buyer should prioritise an independent inspection of the suspension geometry and bush wear , particularly the rear coil springs and track rods , which are common failure points in high-mileage Jaguars. The brake system warrants close examination, as repeated failures (even without explicit logs) could point to binding calipers, warped discs, or deteriorated master cylinders. Structural corrosion should be assessed at the subframe, sills, and exhaust mounts , as rust can compromise wheel bearing integrity and exhaust gas containment. The fuel system , including injectors and fuel lines, may also require scrutiny, given the car’s age and the potential for stagnant fuel causing clogging or leaks. The absence of advisories in the latest pass does not guarantee these areas are sound—only that they did not fail the tester’s basic checks.
