2009 Jaguar XF 3.0L Diesel · GU09 KXB

The vehicle presents a concerning roadworthiness profile characterized by a clear trend of worsening structural integrity. While it passed its most recent MOT in September 2025 at 131,651 miles, this followed a major failure just one month prior. The tester previously identified severe corrosion on the offside rear sub-frame and mounting areas, which significantly reduced structural strength. Although the subsequent pass downgraded these findings to corrosion not seriously weakened, the presence of rust across the integral body structure and subframe indicates the vehicle is entering a critical stage of age-related decay. At 131,651 miles over 17 years, the Jaguar has averaged approximately 7,744 miles per year, which aligns with typical annual usage for a luxury saloon of this age. The record shows a period of consistent activity with nearly 9,000 miles driven between August 2023 and July 2024. However, the rapid progression from 2024 to 2025, where only 1,872 miles were recorded between the failure and pass, suggests that while the mileage is not excessively high, the components are failing due to age rather than sheer mileage. A buyer must prioritize a thorough physical inspection of the underbody to assess the extent of the reported corrosion. The 2025 failure regarding the subframe and integral body structure suggests that the structural integrity of the chassis is compromised and requires close monitoring. Furthermore, the previous failure of front upper suspension ball joint dust covers and multiple tyre-related defects indicate a history of reactive rather than proactive maintenance. Attention should be paid to any signs of bubbling paint or fresh weldwork to ensure the structural repairs made between the last two tests were actually effective.
