A front‑end structural weakness dominates the MOT record – the 2020 dangerous finding that the front suspension arm attachment bracket was insecure still casts a long shadow, even though later tests have shown a pass. The pattern of recurring advisories for suspension ball‑joint play, wishbone bush movement and a deteriorated anti‑roll bar dust cover, combined with repeated corrosion notes on rear body structures, indicates that the vehicle’s chassis and suspension have required repeated attention. The most recent 2021 pass confirms that the critical safety items were remedied, yet the persistence of corrosion advisories and minor leaks suggests the underlying issues have not been fully resolved. At 173,129 mi spread over roughly 29 years the average annual mileage sits near 6,000 mi, well below the typical 10‑12 000 mi for a car of this age. Such low utilisation can be a double‑edged sword: consumables such as brakes, tyres and bushings may have experienced less wear, but prolonged periods of inactivity often accelerate rust formation, especially on the rear sills that have already been flagged. The mileage history shows no large spikes or gaps that would hint at a sudden high‑stress usage phase, reinforcing the likelihood that the vehicle has spent considerable time stationary between journeys. When inspecting the suspension, feel for any clunk, knock or excessive play when the car is driven over uneven surfaces; a loose front arm bracket or worn ball joints will manifest as a vague shudder or steering wobble, particularly under braking. Examine the rear bodywork for flaking paint, bubbling rust or any signs of panel distortion around the near‑side and off‑side rear sills, as the advisories note corrosion that, while not yet deemed structurally critical, could progress if moisture ingress is unchecked. Verify that the exhaust system is free of audible leaks and that there is no oil seepage around the engine bay or under the vehicle – the recurring “slight leak” notes mean you should look for fresh oil stains on the undertray or a pungent oil smell after a short run. Finally, confirm that all lighting functions correctly: the off‑side stop lamp, rear direction indicator and headlamp aim must be verified, as these were previously recorded as failures. Inspect the tyre tread depths to ensure none are still at the legal limit, and watch for uneven wear that could betray mis‑alignment or worn suspension components. A brief road test should include a steady‑state cruise to listen for any abnormal wind‑noise or rattles from the rear structure, and a gentle brake application to check for judder or pulling, which would hint at lingering brake or suspension issues that have not yet surfaced in the MOT record.
