1999 Jaguar S-Type 3.0L Petrol · J30 STJ

The vehicle currently holds a valid roadworthiness status following a pass on 31 March 2026. The maintenance trend shows an inconsistent pattern of immediate failure followed by successful rectification. The car failed the test exactly one day prior to its pass in 2026, mirroring a similar failure and pass sequence recorded on 26 March 2025. These recurring failures suggest that mechanical or safety defects are addressed only when prompted by the annual test rather than being managed through a proactive maintenance schedule. At a recorded mileage of 98,396 miles, this 27-year-old Jaguar has averaged approximately 3,644 miles per year. There is a significant gap in the data between the 21 December 2023 test and the March 2025 test, during which the vehicle remained stationary for over fourteen months. Low annual mileage often correlates with the accelerated degradation of rubber-based components, such as suspension bushes, split hoses, and brake lines, which can perish from age despite low mechanical use. A buyer must conduct a thorough physical inspection of the suspension and structural integrity, as the age and low usage profile frequently mask hidden corrosion and perished rubber. The most recent records do not specify the mechanical failures, but the pattern of failing and then passing indicates that the vehicle frequently operates at the limit of legal safety requirements. Focus should be placed on brake calipers, fluid leaks, and the condition of the subframes, which are common points of failure for this model after periods of inactivity. Buying score: 58 Risk level: Medium.
