2006 Jaguar XK 4.2L Petrol · KO51 MON

The vehicle is currently roadworthy, with a recent MOT pass on 30 September 2025 at 78,117 miles. The maintenance trend shows a clear deterioration in mechanical condition over the past two years, as evidenced by the absence of defects in the four prior tests (2021–2024) and the emergence of multiple advisories in the latest inspection. While no failures were recorded, the presence of worn tyres, deteriorated suspension components, and edge damage on front tyres indicates a shift from consistent upkeep to deferred maintenance, suggesting that some critical wear items may have been overlooked during previous service intervals. The mileage profile reflects low annual usage—approximately 3,906 miles per year over its 20-year lifespan—which implies either light use or extended periods of inactivity. This pattern is supported by the steady progression of mileage between tests: roughly 5,000 miles per year across the 2021–2024 period, followed by a slightly higher accumulation of 4,392 miles between September 2024 and September 2025. Such a consistent and modest increase suggests controlled driving habits, but also raises concerns about potential degradation of rubber components, seals, and fluid systems due to infrequent operation. A buyer should conduct a thorough in-person inspection of the rear suspension system, particularly the ball joints and tie rod ends, which showed severe dust cover deterioration in the most recent test—this is a known failure point in Jaguar XK models and can lead to sudden loss of steering control if left unaddressed. The nearside rear tyre approaching the legal limit and the front tyre showing edge cracking indicate that the entire set may require immediate replacement, especially given the age of the vehicle. Additionally, the brake system should be checked for binding calipers and uneven wear on the discs, as these issues are common in older Jaguars with high corrosion risk in the underbody and wheel arches. Structural integrity should also be verified, particularly around the sills and floor pans, as rust can develop silently in this model despite low mileage.
