2008 Jaguar XKR 4.2L Petrol · XK08 SPH

The vehicle remains roadworthy but the maintenance history reveals a clear and worsening trend regarding rear suspension component degradation. While the most recent test in August 2025 at 40,399 miles passed, the tester flagged severely deteriorated dust covers on both rear upper suspension arm ball joints. This issue follows a consistent pattern of failure dating back to 2021, where lower wishbones, rod joints, and track control arms all showed similar deterioration. The persistence of these faults suggests that the rubber components are failing due to age and dry rot rather than mechanical wear from high mileage. The mileage profile is exceptionally low for an 18-year-old vehicle, averaging approximately 2,244 miles per year. The data shows a steady but slow progression, moving from 16,203 miles in 2012 to 40,399 miles in 2025. This low usage explains the overall cleanliness of the engine and drivetrain records, but it correlates with the observed degradation of rubber parts. Long periods of inactivity often cause seals and dust covers to perish, which appears to be the primary driver of the defects in the MOT history. A prospective buyer must conduct a thorough physical inspection of the entire rear suspension assembly. The recurring failures of nearly every ball joint and dust cover over the last four years indicate that a comprehensive overhaul of the rear suspension hardware may be necessary to prevent future component failure. Attention should also be paid to the braking system; the 2018 failure for an offside front binding brake suggests that the calipers or pistons are prone to seizing when not used frequently. Given the low mileage, the buyer should also check for corrosion on brake discs and perished fluid, as these are common issues for vehicles that remain stationary for extended periods.
