1986 Opel Monza 3.0L Petrol · D300 FAE

The most recent MOT test on 2025-08-02 confirms the vehicle passed with no defects recorded, though the preceding test in May 2024 resulted in a failure—despite no specific faults being logged. This inconsistency suggests either an administrative oversight in the test centre’s records or a vehicle that narrowly avoided minor issues not captured in the official report. The lack of recurring advisories or defects in the last two tests implies no obvious pattern of mechanical decline, but the 2024 failure without explanation raises caution. The 2023 tests—both passed and failed at identical mileage—are particularly anomalous and warrant scrutiny, as they imply either a technical error or a vehicle that evaded detection of latent problems. The recorded mileage of 88,857 miles over 40 years equates to approximately 2,221 miles annually, which is unusually low for a vehicle of this age. The gap between the 2022 test at 81,767 miles and the next entry in 2023—just 5,325 miles in 14 months—suggests prolonged periods of inactivity. This could indicate storage rather than active use, potentially accelerating wear on components like suspension bushes, coil springs, and battery health. The absence of mileage between 2024 and 2025 (88,828 to 88,857) further supports this pattern, though the minimal increase may reflect recent reactivation rather than consistent driving. Given the sparse MOT record, a buyer should prioritise an in-person inspection of high-risk areas. The suspension—particularly rear bushes and coil springs—should be checked for excessive play or corrosion, as prolonged static loading can degrade these components. Binding calipers or uneven brake discs, if present, would explain the 2024 failure, though the lack of details makes this speculative. Structural integrity is critical; examine the subframe, sills, and wheel arches for corrosion, as rust can compromise the vehicle’s load-bearing capacity. The electrical system, including the battery and ignition, should also be tested, as older vehicles often suffer from degraded wiring or failing alternators. While the MOT history shows no overt failures, these areas demand thorough examination to confirm they have not deteriorated beyond the test’s scope.
