2002 Jaguar XJR 4.0L Petrol · KA02 AAX

A dominant theme in this XJR’s MOT record is progressive corrosion of the front vehicle structure together with a persistent off‑side front service‑brake binding advisory that has appeared on every test since 2021, even though the latest 2 December 2025 inspection recorded a pass. The car also carries a suite of recurring advisories – rear coil‑spring corrosion, rear differential oil seepage, exhaust‑system rust and sub‑frame corrosion – and suffered multiple major failures for front‑inner chassis corrosion in 2021 and 2024, indicating a long‑standing battle with rust rather than an improving condition. At 119,994 mi the car averages roughly 5,000 mi per year, which is low for a 24‑year‑old model and suggests periods of light use or storage. The MOT history shows regular testing from 2020 onward with no large mileage jumps between examinations, so the low annual accumulation is consistent rather than a recent anomaly. Low utilisation reduces wear on engine and drivetrain components, but it does not mitigate the structural rust that has developed, and prolonged standing can exacerbate under‑seal deterioration and corrosion on exposed metalwork. Prospective buyers should give particular attention to the front‑inner chassis and sill areas that have been flagged as seriously corroded. Look for signs of panel mis‑alignment, creaking or flex when applying steering torque, and any visible rust holes or flaking under the bonnet and wheel arches. The off‑side front brake binding may manifest as a slightly stiff pedal, uneven brake feel, or a pulling sensation when braking; a test‑drive should include firm, progressive stops to detect any pulsation or pull to one side. Inspect the brake pipes for corrosion and ensure there is no fluid leakage around the front‑right and left lines, as past advisories noted heavy rust coating. The rear suspension and differential also merit scrutiny. Check both rear coil springs for sag, uneven ride height or audible knocking over bumps, which would indicate compromised spring integrity from corrosion. Examine the rear differential for oil stains on the under‑carriage and listen for a whining noise that could signal a worsening leak. Finally, verify the condition of the exhaust system and sub‑frame for rust penetration, and confirm that the under‑seal remains intact; any delamination or rust through the under‑seal should be addressed before the vehicle is driven extensively. A thorough chassis and corrosion survey by a qualified mechanic is advisable to quantify the extent of structural repair required.
