2007 Jaguar XKR 4.2L Petrol · K666 AAT

A pattern of consistent roadworthiness interrupted by a recent significant brake system failure defines the mechanical profile of this Jaguar XKR. While the vehicle maintained a clean record for several years, the most recent testing cycle in July 2025 saw a failure due to parking brake efficiency falling below required standards, though this was rectified to achieve a pass on the same day. This sudden emergence of a major brake defect after years of passing without issue suggests a specific component failure or a lack of recent adjustment rather than a gradual decline in mechanical integrity. The recorded mileage of 76,919 miles over a nineteen-year period represents a low annual usage rate of approximately 4,048 miles. This specific usage profile often implies the vehicle has spent significant periods stationary or has been used primarily for short, infrequent trips. Mechanically, such low mileage can mean less cumulative wear on the drivetrain and engine components, but it can also lead to the degradation of rubber seals, suspension bushes, and braking components that rely on regular movement to remain lubricated and free from seizing. Prospective buyers should pay particular attention to the braking system following the July 2025 failure. During a test drive, it is essential to test the parking brake's holding strength on a gradient and check for any unevenness in pedal feel or pulling during deceleration, which could indicate binding calipers or unevenly worn discs. The 2023 advisories regarding nearside and offside rear tyre wear on the edges suggest potential geometry issues. You should inspect the rear suspension bushings and control arms for excessive play, and during the test drive, listen for any knocks or thuds when traversing uneven surfaces or bumps, which may indicate worn suspension linkages. Given the low annual mileage, a thorough inspection of the underside for signs of corrosion or fluid leaks is warranted, as long periods of inactivity can sometimes allow moisture to settle in hard-to-reach areas. While the recent MOT history is relatively clean, the combination of low usage and the recent parking brake failure necessitates a close examination of all hydraulic connections and mechanical linkages to ensure that the components have not become stiff or degraded due to infrequent use.
