Mechanical Assessment

AI-generated interpretation of this vehicle’s MOT record — not an official statement and not a substitute for an independent inspection.

The vehicle passed its most recent MOT on 8 January 2026 at 29,678 miles, confirming it remains roadworthy. The maintenance trend is stable. The only advisories recorded concern worn front suspension bushes, a condition first noted during the failed test in January 2024 and still present two years later. This indicates a slow, non-progressive wear pattern rather than a sudden failure. No new mechanical defects have emerged since the last successful test, suggesting consistent, if minimal, upkeep. At roughly 3,298 miles per year, this SEAT Mii has covered exceptionally low mileage for a nine-year-old car. The MOT history supports this, with annual mileage increases of approximately 3,000 to 3,500 miles between tests. There are no gaps in the record; the vehicle has been tested every January since 2020. This consistent, low-use pattern implies the car has likely spent periods stationary, which can contribute to component seizing or seal degradation, though no such issues have yet surfaced in the MOT records. A buyer should prioritise inspecting the front suspension in person. Both nearside and offside front lower suspension arm bushes are worn, as flagged in the latest test. While not yet causing excessive movement, worn bushes can lead to imprecise steering and accelerated tyre wear. Given the car's age and low mileage, check for signs of the vehicle standing for extended periods: look for flat spots on tyres, stiffness in the steering rack, and ensure the handbrake operates smoothly without binding. The rear brake system, given the previous tyre wear noted in 2024, should also be examined for uneven wear or caliper stiffness. Finally, confirm the horn and fuel cap, which caused the January 2024 failure, are functioning correctly, as these are simple but essential safety items.
