1998 Daihatsu Sirion 1.0L Petrol · S749 UKJ

The most recent DVSA test, dated 22 October 2021, recorded a PASS, indicating that the vehicle met the statutory road‑worthiness criteria at that time. However, that same date also shows a FAIL for a number of serious items, suggesting that the pass was only achieved after remedial work was carried out. Looking back through the eight‑year MOT record, the early years (2019‑2020) were dominated by dangerous tyre defects, chassis corrosion and lighting failures, while the 2018‑2016 period was clean. The pattern therefore points to a recent improvement in maintenance, but the recurrence of major faults in the latest test highlights that the vehicle’s condition is still marginal and requires careful scrutiny. With a recorded 43 741 mi on a 1998 model the average annual mileage works out at roughly 1 560 mi per year, which is well below the typical 8‑12 000 mi for a car of this age. Such low utilisation often indicates long periods of storage or very light use, both of which can accelerate age‑related deterioration. Rubber components, especially tyres and seals, can perish from lack of flexing, while metal parts may develop surface rust when the car sits idle. Conversely, the low mileage means that high‑wear items such as the clutch, gearbox and engine internals have likely seen relatively little mechanical stress, but they may still suffer from oil degradation and seal hardening simply due to time. A prospective buyer should give the tyre set the most thorough examination. The MOT history records tears, bulges, ply exposure and perishing on all four wheels, so inspect each tyre for side‑wall cracks, uneven tread wear, foreign objects or any sign of separation. Verify that the tyre pressures are correct and that the wheels are free of vibration when the car is driven at moderate speed; any shudder or thumping may indicate internal damage. The constant‑velocity joint boot on the near‑side front drive shaft was noted as split, so check for grease leakage, clicking noises on acceleration and play in the joint. The excessive engine oil leak reported in 2021 must be confirmed – look for fresh oil stains under the engine bay, ensure the oil level is stable and consider a compression test if the leak appears unresolved. Suspension components have repeatedly shown deteriorated ball‑joint dust covers and rear shock‑mount corrosion; examine the lower control‑arm bushes, ball‑joint caps and rear sub‑frame for excessive play, rust or cracked rubber, and listen for clunks when braking or traversing bumps. All external lights, especially the nearside stop lamp and repeater, should be tested for proper operation, and the registration plates must be legible to avoid a future failure. Given the vehicle’s age and the likelihood of prolonged storage, time‑based checks are essential. Test the 12 V battery with a load tester; a battery older than ten years often loses capacity and may fail under load. Inspect the condition of all fluid reservoirs – engine oil, brake fluid, coolant and power‑steering fluid – for colour, level and any signs of moisture, and be prepared for a full service if the last change is unknown. Examine the chassis, particularly the rear sub‑frame and shock‑mount area, for surface rust that could have progressed to structural weakening. Finally, verify that the service book contains stamps for regular oil changes, timing‑belt or chain maintenance (if applicable), and that any outstanding recalls have been addressed. A thorough visual and road‑test appraisal, focusing on the points above, will give a realistic picture of whether the Sirion remains a safe and economical purchase.
