1980 Saab 900 2.0L Petrol · PMY 487W

A 46-year-old SAAB 900 with this MOT history tells a mechanical story dominated by recurring age-related corrosion on rear suspension components and intermittent front-end steering and lighting defects, rather than catastrophic structural or powertrain concerns. The most recent test on 12 January 2026 was a pass, but it carried four advisories, three of which were carried over or echoed issues flagged in the prior failure two months earlier, suggesting persistent wear rather than items that have been resolved. In November 2025 the car failed on three majors: an inoperative horn, an offside front main beam headlamp not working, and critically, a single-line front parking brake lacking adequate effort at a wheel, alongside advisories for front oil leak and both rear coil springs corroded. Earlier in 2024 the vehicle failed on both front track rod ends being seriously misaligned and a missing nearside front steering rack gaiter, before passing later the same month with no advisories. Between 2021 and 2023 the record was largely unremarkable aside from a 2021 headlamp aim failure and a 2023 advisory on track rod end play, so the overall trajectory shows a vehicle whose roadworthiness has measurably deteriorated over the last two years, with advisories and defects concentrating in braking, steering, lighting, and rear suspension. The recorded mileage of 130,400 miles across 46 years equates to approximately 2,835 miles per year on average, which is low for a car of this vintage and suggests a long-term pattern of either light use or extended periods off the road. The MOT testing pattern supports periods of dormancy: tests are clustered in 2021 (two), 2022, 2023, and then a gap before the closely spaced 2024, 2025, and early 2026 entries, indicating either a recent return to regular use or that the vehicle has only recently become road-licensed again. Mechanically, low annual mileage on a classic of this age tends to accelerate corrosion in components that benefit from regular heat cycling and lubrication, such as brake calipers, rear coil springs, and rubber brake hose ferrules, all of which appear in the recent advisories. Conversely, low mileage generally preserves the engine, clutch, and gearbox internals from wear, though the persistent front oil leak advisory hints that age-related gasket and seal degradation is already underway. A prospective buyer should prioritise a close inspection of the rear coil springs, which have been flagged for corrosion on both sides in both the 2025 failure and the 2026 pass, as corrosion here can progress to fracture under load. On test drive, listen for any clonking or creaking from the rear suspension over speed humps and undulating roads, and visually check the springs for surface pitting or flaking when viewed from underneath. The brake hose ferrules on both rear hoses have been flagged with slight corrosion on the 2026 test; inspect the braided or rubber hoses for bulging, cracking, or weeping, and check for a spongy or low pedal that could indicate fluid migration past corroded internals. The front parking brake failure in November 2025 is a serious safety item on a single-line braking system, so confirm whether the actuator, cables, or rear caliper handbrake mechanism have been rectified and verify firm handbrake application with the vehicle on an incline before purchase. The steering advisories deserve particular attention given the 2024 misalignment failure on both front track rod ends and the 2023 ball joint play advisory. On test drive, expect any wandering, tramlining, or uneven steering response, and check for uneven front tyre wear, which would confirm persistent geometry or component issues. The steering rack gaiter missing in 2024 should be confirmed as replaced, as a torn or absent gaiter allows water and grit into the rack, dramatically shortening its life, and on a 46-year-old SAAB 900 replacement racks are scarce. The front oil leak advisory has now appeared across two consecutive tests, so inspect the sump, cam cover, and front crankshaft seal for fresh seepage on a cold engine. Finally, the lighting defects in 2025 (horn and main beam) suggest possible earth or switch faults that may have been remedied, but verify operation of all headlamp functions including dip, main, and flash before purchase, and confirm the front oil leak is not worsening as it has now been recorded as an advisory for two consecutive tests.
