2005 Jaguar S-Type 3.0L Petrol · FG55 OKH

The vehicle currently holds a roadworthy certificate, but the maintenance history reveals a concerning trend of neglect. While it passed its most recent test on 22 April 2026 at 112,039 miles, this followed a failure just one week prior. The April 2026 failure was severe, involving significant structural corrosion on the inner integral body structure of both sills. Although these specific faults were cleared for the subsequent pass, the presence of deep rust on the chassis members suggests the structural integrity is at risk and requires immediate, expert verification. At 112,039 miles, this 21-year-old Jaguar has covered a low average of approximately 5,335 miles per year. The mileage progression is consistent over the last two years, with 670 miles recorded between April 2025 and April 2026. However, low mileage often correlates with the degradation of rubber components and seals due to inactivity, which is reflected in the record. The recurring oil leak noted in both 2025 and 2026 indicates a persistent mechanical issue that has not been addressed by the previous owner. A physical inspection must prioritise the structural condition of the sills to ensure the corrosion reported in April 2026 has been properly treated or merely masked. The braking system also shows signs of deferred maintenance; the April 2026 test flagged thin rear brake pads and pitted discs, along with severely deteriorated dust covers on both rear inner suspension rod ball joints. A prospective buyer should also inspect the suspension ball joints and anti-roll bar links, as these have shown a history of failure or imminent risk in recent tests. The persistent front oil leak requires a professional diagnosis to determine if the source is a minor gasket or a more costly engine seal failure.
