2006 Daihatsu Terios 1.5L Petrol · NU56 FHJ

The 2006 Daihatsu Terios presents a mixed but broadly stable mechanical picture at its most recent MOT on 12 January 2026 at 104,018 miles. That test passed with a cluster of minor advisories rather than a single dominant failure. A minor central exhaust gas leak, slight play in the nearside front track rod end ball joint, and worn lower suspension arm pins or bushes on both front corners were flagged. None of these items were marked as serious or dangerous, and the vehicle passed without any failures. Comparing the last five tests, the trend is not cleanly improving or worsening; it is a steady accumulation of age-related wear and minor corrosion advisories that have been managed within acceptable limits each year. The 2023 test at 100,958 miles was entirely defect-free, but the two most recent tests have each returned three to four minor advisories, suggesting the vehicle is now entering a phase where routine component refreshment is needed rather than being in a state of neglect. At roughly 104,000 miles over nearly twenty years, the annual average sits close to 5,200 miles. That is low for a vehicle of this age and points to light, local use rather than sustained motorway mileage. The MOT record supports this interpretation. Between the August 2021 test at 96,749 miles and the January 2023 test at 100,958 miles, the vehicle covered approximately 4,200 miles in just over fifteen months. From January 2023 to January 2026, the mileage rose only from 100,958 to 104,018, a gain of roughly 3,060 miles across three full years. The gap between the 2021 and 2023 tests is notable, and the very slow accumulation since then raises the possibility of extended periods standing. Low mileage can preserve mechanical components in some respects, but prolonged inactivity tends to accelerate corrosion of brake lines, exhaust systems, and exposed suspension linkages, which is exactly what the record shows. A prospective buyer should focus the physical inspection on three areas. First, the underside and structural mounting points, given the repeated corrosion advisories. The January 2024 test at 102,071 miles flagged corrosion to the rear integral body structure, both front inner arches, the front sub-frame, and both rear brake pipes, all noted as not significantly weakened at that time. The underside was recorded as covered in underseal in both 2025 and 2026, which can mask active corrosion rather than prevent it. A thorough check of the chassis rails, sub-frame mounting points, and brake pipe condition underneath the vehicle is essential, particularly around the rear suspension mounting areas where sealed repairs were noted as far back as August 2021 at 96,749 miles. Second, the front suspension and steering components deserve close attention. Slight play in the nearside front track rod end ball joint has appeared in both the 2025 and 2026 tests, and worn lower suspension arm pins or bushes on both sides were flagged in 2026. These are wear items consistent with age and mileage, but the recurrence suggests they have not been replaced recently and may need attention soon. Third, the exhaust system should be inspected for the minor gas leak noted at the centre section in 2026, alongside the defective rear exhaust mounting recorded in 2024. A buyer should also verify the condition of all brake discs, pads, and tyres, as low annual mileage does not eliminate consumable deterioration from age.
