1999 Mitsubishi Galant 2.0L Petrol · T836 AGX

The most recent MOT on 12 February 2026 was passed, but it carried a suite of advisories covering the rear registration plate, front‑exhaust leak, severe corrosion of the rear wheel arches, a cracked off‑side rear tyre and corroded rear disc back‑plates. Over the last seven years the vehicle has consistently passed the test, yet the number of recurring advisories – particularly the exhaust leak, brake‑pipe corrosion and body‑work rust – has not diminished, indicating a maintenance pattern that is holding the car road‑worthy but not addressing underlying wear. The single failure recorded in February 2025 was limited to a non‑functional windscreen washer, suggesting that functional safety items have generally been kept in service while cosmetic and corrosion‑related issues have been left to advisory status. At 141 057 miles the Galant averages roughly 5 200 miles per year, well below the typical annual mileage for a vehicle of its age. This low utilisation often points to periods of limited use or prolonged storage, which can accelerate age‑related degradation such as tyre perishing, battery sulphation and corrosion in hidden areas. The modest mileage means that high‑wear components such as the engine, gearbox and drivetrain are unlikely to be near the end of their service lives, but the long exposure to the elements without regular movement can allow rust to develop on suspension mounting points, brake pipe fittings and the rear bodywork that the MOT advisories have highlighted. A prospective buyer should give particular attention to the front‑exhaust system; a minor leak can allow exhaust gases to escape near the cabin, potentially causing a faint sulphur smell or increased engine noise, and may indicate a cracked manifold or deteriorated gasket that will need resealing or replacement. The brake‑pipe corrosion noted on both front and rear lines, often coated in grease, is a sign of rust‑induced weakening; inspect the pipes for any signs of pin‑hole leaks, especially when applying the brakes, and listen for a faint hissing or loss of pedal firmness. The rear disc back‑plates and wheel‑arch panels show significant rust – check the discs for uneven wear, scoring or wobble, and verify that the calipers move freely without binding. The off‑side rear tyre is already listed as slightly damaged or perishing; examine both tyres for sidewall cracks, dry rot and tread depth, and be prepared to replace them if the rubber feels brittle or the tread is below the legal minimum. Given the vehicle’s age and low mileage, time‑based maintenance is as critical as mileage‑based service. Verify the condition of the 12 V battery, looking for swollen cells or a voltage below 12.4 V after a short load test, and consider a replacement if the battery is more than five years old. Drain and replace all engine and brake fluids, as they can absorb moisture and lose effectiveness after several years even with limited use. Inspect suspension bushings, ball joints and shock absorbers for any play, clunking or leaking when the car is pushed over bumps, and check the steering rack for excessive free play. Finally, ensure the rear registration plate is legible and securely mounted, and confirm that any cosmetic corrosion on the wheel arches or body panels has not progressed to structural compromise. Addressing these points before purchase will mitigate the risk of sudden failures and provide a clearer picture of the car’s long‑term roadworthiness.
