1979 Jaguar XJS 5.3L Petrol · GPV 105T

The vehicle currently holds a clean roadworthiness status following a successful test in January 2024 at 45,952 miles. This result represents a significant improvement in maintenance standards compared to the major failure in 2018. While the 2020 and 2024 tests showed no defects, the history indicates that critical mechanical and structural issues were previously addressed and the vehicle has since maintained stable operation over the last six years. The mileage profile is exceptionally low for a 47-year-old vehicle, averaging fewer 1,000 miles per year. The data shows long periods of inactivity, evidenced by only 102 miles driven between July 2020 and January 2024, and just 70 miles between August 2018 and July 2020. While this low usage limits wear on the drivetrain and engine, such extended standing often leads to degradation of rubber components, perished seals, and fluid breakdown that mileage records cannot fully capture. A buyer must conduct a thorough physical inspection of the structural integrity, specifically the offside front outer vehicle structure which failed in July 2018 due to significant corrosion and reduced rigidity. Although this was later rectified, the age of the chassis demands close scrutiny for recurring rust in these areas. You should also verify the coil springs and wheel bearings, as these were flagged for corrosion and play in 2018 and required replacement to pass the subsequent test. The braking system requires specific attention given the severe 2018 failure where both service and parking brakes fell below efficiency thresholds alongside a pedal failure to release. Given the low mileage and long stationary periods, there is a risk that calipers have seized or brake lines have suffered from internal corrosion. Ensure the exhaust system remains secure and free of leaks, as multiple points of the assembly were noted as insecure in the past..
