1965 Jaguar Saloon 3.7L Petrol · CSP 333C

The vehicle presents a generally stable mechanical condition, though the most recent test on 2026-04-09 at 24,287 miles reveals a persistent weep that demands attention. The tester issued an advisory for an oil leak that was not deemed excessive at that time. This recurring defect mirrors entries from 2022 and 2021, indicating a long-term, low-level oil seepage that has not worsened into a dangerous failure but requires monitoring. The maintenance trend remains stable rather than deteriorating, as the car has consistently passed its tests after addressing immediate safety risks. The mileage accumulation is remarkably low for a 1965 vehicle, averaging just under 400 miles annually over its lifespan. Between the tests on 2022-01-19 at 22,610 miles and 2023-07-12 at 23,282 miles, the car covered 672 miles in eighteen months. The subsequent period from July 2023 to April 2025 saw only 586 miles added, and the most recent year up to April 2026 accounted for 419 miles. Such sporadic use suggests prolonged periods of standing, which often takes a toll on rubber components and brake surfaces despite the low distance covered. A physical inspection must prioritise the source of the recurring oil leak, paying close attention to transmission seals and engine gaskets that weep due to infrequent use and thermal cycling. The 2021 failure for an excessively binding nearside rear service brake and a non-functioning headlamp main beam suggests previous neglect of minor electrical and hydraulic systems, so a thorough check of the braking system for sticking calipers and corroded linkages is wise. Standing for extended periods frequently causes flat-spotted tyres, perished suspension bushes, and surface corrosion on brake discs. Examine the underside thoroughly for structural integrity, as dormant classic cars often suffer from hidden corrosion in subframes and sills that MOT tests cannot fully evaluate.
