2006 Jaguar XK 4.2L Petrol · FH06 NNT

The vehicle is currently roadworthy following a pass in April 2026, but the maintenance history indicates a worsening trend regarding structural and mechanical degradation. While the most recent test at 88,012 miles cleared the car, the failure just one week prior at 87,999 miles reveals that critical steering components were neglected until the deadline. The persistence of corrosion on the rear sub-frame across multiple tests points to an ongoing structural issue that is likely progressing, despite not yet reaching the threshold for immediate failure. At 88,012 miles, this twenty-year-old Jaguar has averaged approximately 4,401 miles per year. This low annual usage often leads to the degradation of rubber components and seals rather than simple mechanical wear from distance. Between April 2024 and March 2025, the car covered only 1,208 miles, yet it suffered a failure for a coolant leak and a leaking brake pipe. This pattern suggests the vehicle may sit stationary for long periods, allowing hydraulic lines and cooling systems to perish, leading to fluid failures. A buyer must conduct a thorough inspection of the rear sub-frame to determine if the noted corrosion has reached a point of requiring welding or total replacement. The failure of both front track rod end dust covers in 2026 indicates that the steering linkage is reaching the end of its life, requiring a check for play. Furthermore, the offside front brake flexi pipe and coolant leak identified in 2025 necessitate a pressure test of the entire cooling system and an inspection of all hydraulic lines to prevent future catastrophic failures.
