1990 Porsche 944 3.0L Petrol · G150 JPW

The vehicle’s most recent MOT test on 2026-02-25 confirmed it as roadworthy, though the preceding failure on 2026-02-19—just six days earlier—raises immediate concern over either a temporary administrative error or a critical oversight in pre-test preparation. The pattern of alternating pass/fail results at identical mileages (181,773) over the past two years suggests either a deliberate retesting strategy or a recurring but undocumented issue that evaded detection. The absence of recorded defects in any of these tests does not preclude underlying problems, particularly given the vehicle’s age and the lack of advisories to prompt further inspection. The most recent pass, however, provides a baseline for current compliance, though the narrow margin between tests implies a need for vigilance. The recorded mileage of 181,773 miles over approximately 36 years—averaging just over 5,000 miles annually—indicates either very light usage or prolonged periods of inactivity, which can accelerate certain forms of degradation. The mileage remained static between the 2024 and 2025 tests, suggesting the vehicle was not driven between February 2024 and February 2025, a span of 12 months. While this could mitigate wear on high-mileage components like brakes or suspension, it also increases the risk of fluid degradation (hydraulics, coolant, transmission) and static-related issues such as tyre dry-rotting or corrosion development. The lack of mileage progression between tests further complicates assessing wear trends, as critical components may not have accumulated sufficient usage to reveal their true condition. Given the vehicle’s age and the absence of recorded advisories or defects, a buyer should prioritise an in-person inspection of the suspension system, where rubber bushes and coil springs are particularly vulnerable to fatigue and corrosion after three decades. The binding brake calipers or uneven wear patterns—common in older Porsche models—should be checked for, as these often go unnoticed without dynamic testing. Structural integrity, particularly around the subframe and sills, warrants scrutiny for corrosion, as does the exhaust system for leaks or excessive rust that could compromise emissions or structural support. The engine bay should be examined for fluid leaks, particularly around the timing belt cover and power steering components, while the interior should reveal any signs of water ingress or electrical faults that might have been overlooked in MOT testing. The tyres, despite the low mileage, should be assessed for uneven wear or dry-rotting, especially if the vehicle has spent extended periods stationary.
