2006 Jaguar XK 4.2L Petrol · SK56 ASK

The Jaguar XK’s most recent MOT test on 2025-12-09 at 80,236 miles confirms it remains roadworthy without defects, maintaining a flawless pass record across all five tests since 2021. This consistency suggests the vehicle has been subjected to either diligent servicing or benign usage conditions, with no recurring advisories or failings to indicate worsening mechanical issues. The lack of advisories—particularly for critical systems like suspension, steering, or exhaust emissions—implies no hidden degradation requiring urgent attention. However, the absence of defects does not preclude wear beyond MOT thresholds, such as minor suspension bush deterioration or brake pad thinning, which would only manifest in a thorough mechanical inspection. The recorded mileage of 80,236 miles over 20 years—approximately 4,012 miles annually—is unusually low for a vehicle of this age, suggesting it has spent extended periods either stored or used lightly. There are no abrupt mileage jumps between tests, and the intervals between MOTs (around 12–14 months) align with standard practice, though the lack of service records complicates assessing maintenance discipline. The steady, modest mileage could imply the vehicle has been preserved rather than actively driven, which may have mitigated some wear, but it also raises questions about whether critical components like the engine bay, underbody, or drivetrain have been regularly inspected for corrosion or fluid leaks. A buyer should prioritise an in-person inspection focusing on the suspension’s coil springs, bushes, and damper condition, as these are common points of failure in high-mileage Jaguars and often exceed MOT tolerances before failing outright. The brakes, particularly the rear calipers and discs, should be checked for uneven wear or binding, as the rear braking system in this model has historically been prone to premature wear. Underbody corrosion is another critical concern—inspect the sills, subframe, and exhaust system for rust penetration, especially if the vehicle has spent time in wet or coastal environments. Finally, verify the integrity of the exhaust system for leaks or excessive corrosion, as catalytic converter failures are not uncommon in this era of Jaguar, and emissions-related defects were not recorded in any MOT.
