2003 Jaguar XKR 4.2L Petrol · MH03 WZT

The vehicle passed its most recent MOT in July 2025, confirming current roadworthiness, but the maintenance trend shows a pattern of recurring structural and tyre wear issues that suggest deferred upkeep. The suspension mounting corrosion flagged in 2025 is a direct continuation of concerns first noted in 2022 regarding heavy undersealing that hindered inspection, indicating a persistent vulnerability in the underbody. Mileage progression is slow and consistent, with only 4,912 miles accumulated between May 2020 and July 2025, averaging under 1,000 miles per year. This low annual usage aligns with the car’s age and implies limited daily driving, yet it does not mitigate the risk of material degradation from prolonged exposure to moisture and road salt, particularly given the undersealing and corrosion issues. The gap between the 2021 and 2022 tests is unusually short at just eight months, which may reflect a precautionary retest after tyre wear was flagged, rather than routine annual servicing. A buyer must inspect the sills, subframe mounting points, and surrounding structural steel for active corrosion, as the 2025 advisory confirms this is not a one-off observation but an ongoing condition. The repeated tyre edge wear across both rear and front axles since 2021 points to misalignment, worn suspension bushes, or incorrect inflation, and the tyres should be replaced regardless of tread depth due to uneven degradation. The slight play in the rear wheel bearing noted in 2021 was not reflagged in later tests, but it should still be checked — bearing wear often progresses silently. The heavy undersealing applied since 2023, while intended to protect, may now be concealing rust or moisture traps; a full underbody strip and visual inspection are essential before purchase.
