2006 Jaguar XK 4.2L Petrol · J55 GCA

The Jaguar XK currently holds a failed roadworthiness status following the 9 September 2025 test at 144,253 miles, where the tester recorded a failure with no specific defects listed. Prior to this, the vehicle passed four consecutive tests between 2021 and 2023 with no defects or advisories recorded, indicating a previously stable maintenance trend that has now broken. The recent failure introduces uncertainty regarding the car's present mechanical condition, as the DVSA entry lacks the granular fault detail normally expected on a fail. Mileage accumulation across the record is low and consistent with a lightly used 20-year-old vehicle. The odometer moved from 141,715 miles at the 3 November 2021 test to 142,744 miles in October 2022, then 143,626 miles in October 2023, and 144,253 miles by the 2025 failure. This equates to under 1,000 miles per year across that span, well below the roughly 7,200 annual average for the model's age. A notable gap exists between the October 2023 pass and the September 2025 failure, a near two-year interval exceeding the standard 12-month cycle, suggesting the car stood unused or was off-road during that period. The sparse MOT history offers no flagged wear on suspension bushes, brake discs, coil springs, or structural corrosion across the passes, so no recurring fault trend is evident from the data. The unexplained 2025 failure with no defects recorded warrants direct investigation, as DVSA systems occasionally omit free-text fault lines on administrative fails such as documentation or emissions equipment presence. A buyer should commission a physical inspection of the brake calipers for binding, check exhaust emissions against current limits, and examine subframe and sills for corrosion given the vehicle's age and the long lay-up implied by the mileage gap. Low use followed by a failed test often masks perished rubber components and seized mechanical parts that a stationary car develops out of sight.
