1999 Jaguar XKR 4.0L Petrol · C1 SGT

The most recent MOT, carried out on 26 April 2024, was passed but returned several advisories concerning the rear anti‑roll bar linkage bushes on both sides and superficial corrosion of the outer integral body structure. Earlier tests show a consistent pattern of the same rear anti‑roll bar wear, occasional rear tyre damage and a one‑off note of front lower suspension arm ball‑joint play in 2021. Apart from a single failure in 2014 that appears to have been rectified, the vehicle has passed each subsequent test, indicating a generally stable maintenance record with wear items now being flagged before they become prohibitive failures. With 73 214 miles recorded on a 1999 model, the average annual mileage works out at roughly 2 700 mi, well below the typical usage for a car of this age. Such low utilisation often points to extended periods of storage or very light use, which can be as consequential as high mileage. Age‑related deterioration of rubber components, seals, and corrosion‑prone areas may have progressed despite the modest mileage, and any long gaps between journeys can exacerbate battery depletion and fluid breakdown. When inspecting the car, pay particular attention to the rear anti‑roll bar linkage bushes; feel for any clunk or looseness when applying a firm steering input or when the rear wheels are forced over a bump. Examine the rear tyre sidewalls for cracking, perishing or bulging, especially where the MOT noted slight damage, and check for uneven tread wear that could indicate mis‑alignment or worn suspension bushings. Inspect the outer body panels, wheel arches and under‑carriage for surface rust that may have advanced beyond the advisory stage, and verify that the structural integrity of the integral body remains sound. Test the parking brake for firm engagement and ensure the rear brake pedal on the nearside provides normal effort, as these systems previously failed to meet the required efficiency. Confirm that the nearside stop lamp operates correctly and that the front lower ball‑joint on the off‑side shows no excessive play when the wheel is rocked at the 12 o’clock position. Given the vehicle’s age, a thorough visual and tactile survey of age‑related items is essential. Check the 12 V battery for terminal corrosion and verify its cranking voltage; a battery that has sat idle for years may need replacement. Inspect all fluid reservoirs – engine oil, coolant, brake and power‑steering fluids – for colour change, sediment or loss of level, and consider a complete fluid change if service stamps are absent. Look at the condition of the brake discs for surface rust or scoring, and ensure the calipers move freely without binding. Examine the rubber hoses, drive‑belt, and suspension bushings for hardening or cracks, and confirm that the exhaust system is free of leaks or excessive corrosion, particularly around the joints and mounts. A comprehensive test‑drive should reveal any noises such as squeaks from worn bushings, shudder under braking, or vibrations that could betray hidden wear, allowing you to negotiate any necessary remedial work before purchase.
