2008 Mazda 5 2.0L Petrol · YL57 AAX

The most recent MOT on 4 February 2026 was passed, although it carried advisories for under‑body corrosion, corroded inner sills and chassis/sub‑frames, a corroded rear coil spring and a front brake disc that is worn, pitted and scored but not yet seriously weakened. Over the past three years the vehicle has swung between passes and failures, with major failures recorded in early‑2025, early‑2024 and early‑2023 for items such as a fractured rear coil spring, a split CV‑joint boot and an exhaust leak. While the latest test shows the car is currently road‑worthy, the pattern reveals a steady accumulation of age‑related wear and corrosion rather than a clear improvement, suggesting that remedial work has been applied only enough to clear the MOT but underlying deterioration remains. At 146 688 miles the car averages just over 8 000 miles per year, a figure that sits comfortably within the normal usage envelope for an eighteen‑year‑old family MPV. There are no obvious periods of unusually high mileage that would point to accelerated component fatigue, but the relatively low annual run‑off also implies the vehicle may have spent significant time standing, a condition that tends to accelerate rust on the under‑body and promote fluid degradation. The mileage is sufficient to have consumed most consumables – brakes, tyres, suspension bushes and engine oil – and the recorded wear on those items is consistent with the distance covered. A prospective buyer should give particular attention to the extensive corrosion noted on the under‑body, inner sills, sub‑frames and rear coil spring. Inspect the chassis for any rust‑induced holes, especially around the rear suspension mounting points and the rear coil spring housings; any flex or audible clunk when the vehicle is driven over bumps may indicate that the structural integrity is compromised. The rear coil spring that was recorded as fractured in early‑2024 should be examined for cracks or broken coils, and the front coil spring corrosion should be checked for loss of stiffness, as a weakened spring will manifest as a sagging rear ride height or uneven tyre wear. The CV‑joint boots on both front drive shafts have shown severe deterioration, so the joints themselves should be inspected for splatter or clicking when turning; a failing boot will eventually allow dirt ingress and joint failure, often heard as a rhythmic clicking or felt as a vibration under acceleration. The exhaust system still carries a major leak advisory from 2025, so a visual inspection for cracks or holes, especially around the manifold and rear pipe, is essential – a leaking exhaust can produce a noticeable rumble and may allow fumes to enter the cabin. Brake components also require immediate scrutiny. Both front brake discs have been flagged as pitted and scored, and the front pads are already thin, which together can lead to reduced braking efficiency, pedal pulsation and a squealing noise under heavy braking. The rear pads were reported as thin in early‑2024, so the rear braking balance should be tested for any pull to one side. Given the age of the vehicle, the brake fluid should be replaced if it shows any moisture or discoloration, as fluid degradation can cause internal corrosion of the calipers. Finally, check the lighting – headlamp aim is still out of adjustment and several position lamps have failed in the past – and verify that the rear registration plate is legible and securely mounted. A full service history check, a battery load test, tyre sidewall inspection for age‑related cracking, and a top‑up of all service fluids will give a clearer picture of the car’s overall condition before committing to purchase.
