2012 Jaguar XK 5.0L Petrol · RFS 607

A persistent theme of age‑related corrosion and minor wear runs through the MOT record, with brake‑line ferrules, sub‑frame panels and several suspension dust‑covers repeatedly flagged as deteriorating, while tyre damage and wheel distortion have also surfaced on multiple occasions. The most recent test on 19 February 2026 confirmed a pass but listed an off‑side front wheel distortion, tyre wall damage and severely deteriorated inner‑rod ball‑joint dust‑covers, underscoring that the vehicle’s structural and braking components are showing a gradual decline rather than an isolated fault. At 51 121 miles over fourteen years the annual average is roughly 3 600 mi, well below typical usage for a Jaguar XK of this vintage. Such low mileage often indicates periods of limited running or storage, which can accelerate corrosion of exposed metal parts and rubber components despite the modest wear on moving parts. The MOT chronology shows no large mileage jumps between tests, suggesting the vehicle has not been subjected to high‑stress driving, yet the age‑related degradation evident in the advisories is consistent with a car that has spent considerable time idle. When evaluating the car, pay particular attention to the braking system: feel for any softening or sponginess in the pedal, listen for air‑bubble noises during initial braking, and inspect the front and rear brake hoses for external corrosion or leakage at the ferrules. Examine the brake discs for surface pitting or scoring that could affect stopping performance, and be prepared for a possible replacement if the wear is more advanced than the advisory suggests. Test the steering and ride quality over bumps; any clunking, knocking or excessive play may reveal the worn rear suspension arm pins, bush wear or the deteriorated dust‑covers on the inner rod ball‑joints noted in 2022‑2023. The sub‑frame corrosion, repeatedly described as present but not yet structurally compromised, warrants a visual inspection for any signs of rust penetration, especially around mounting points, and a chassis check for any audible creaks under load. Tyre condition should be scrutinised for the documented cuts, wall damage and the off‑side wheel distortion, as these can affect handling and may require immediate replacement. Given the accumulation of corrosion‑related advisories, budgeting for new brake hoses, a set of brake discs, fresh suspension bushings and a fresh set of tyres will be prudent, and a comprehensive pre‑purchase inspection by a qualified mechanic is strongly recommended to confirm the extent of rust and to verify that no hidden faults have been missed.
