1995 Porsche 928 5.4L Petrol · 1 NAX

The 1995 Porsche 928 presents a broadly stable mechanical picture, though the most recent MOT on 6 September 2025 at 19,362 miles flagged two new advisories that warrant attention. Both front brake hose ferrules showed slight corrosion, and a transmission oil leak was noted. These are not fresh failures, but they indicate the car is beginning to show age-related deterioration in areas that were clean just nine months earlier. The maintenance trend is neither sharply worsening nor improving; it sits in a holding pattern typical of a low-mileage classic that sees intermittent use rather than daily service. The mileage record tells a consistent story of very light use. Between 22 August 2022 and 6 September 2025, a span of just over three years, the odometer moved only 182 miles, averaging roughly 60 miles per year. The 2024-12-18 failure at 19,277 miles for an out-of-spec Lambda reading on the exhaust suggests the car may have been started and tested after a period of standing, possibly with a cold engine or a marginal catalytic converter. The clean pass the following day at 19,309 miles supports that interpretation. No rapid accumulation or suspicious gaps appear in the record, and the overall figure of 19,362 miles across 31 years is exceptionally low. A buyer should focus the physical inspection on the front brake hoses and transmission area. Corrosion on the hose ferrules is a surface-level advisory today, but on a 30-year-old car it can signal that the rubber itself is ageing and the fittings may seize if disturbed. The transmission oil leak noted in September 2025 needs a clear diagnosis: on a 928, common sources include the output shaft seal, the torque tube seals, or the pan gasket. Oil leaks also appeared in September 2023 and August 2022, so this is a recurring theme rather than a one-off. The nearside front inner rack arm ball joint play flagged in August 2022 was not mentioned in later tests, which could mean it was repaired or simply fell below the tester's threshold, but the steering rack and suspension bushes deserve a close check on a lift. The Lambda-related emissions failure in December 2024, while resolved quickly, hints at a catalytic converter that may be marginal after long periods of inactivity. A thorough cold-start emissions test and an underbody inspection for corrosion on the exhaust and transmission tunnel would be prudent before committing.
