2020 Mercedes-Benz A 1.3L Petrol · LS20 AXM

The most recent MOT on 2 March 2026 was passed, the only items recorded were advisory notes about cuts on the nearside front, off‑side front and off‑side rear tyres that have not penetrated the ply. Earlier in the series the 12 March 2025 test failed only for headlamp aim being too high, a defect that is rectified by simple alignment of the units. Apart from that isolated failure, the vehicle has passed three consecutive annual tests, indicating a generally stable maintenance pattern with no major safety‑critical failures, though the recurring tyre advisories suggest the wheels have been subject to repeated edge damage that has not yet become a legal fault. At six years old the car has logged 25,858 mi, equating to roughly 4,300 mi per annum – well below the UK average for a vehicle of this age. Such low utilisation often points to periods of limited use or prolonged storage, which can be as consequential as high mileage in terms of component ageing. The modest annual run‑off reduces wear on the engine, transmission and suspension, but it also means that rubber compounds, seals and battery cells may have deteriorated from age rather than use, and corrosion can develop on brake discs, calipers and under‑carriage parts if the car has sat for extended spells. When inspecting the tyres, verify that the cuts noted in the MOT have not progressed into the carcass; look for any bulging, cracking of the sidewalls or uneven tread wear that could indicate mis‑alignment or suspension wear. On a test drive listen for a low‑frequency thump or feel a vibration when the steering is held steady, which would signal a need to check the front wheel bearings, suspension bushes and alignment – especially since the headlamp aim issue may have been caused by an out‑of‑spec steering geometry. Examine the tyre pressure retention over a short drive; a slow loss could be a sign of a puncture or bead damage that will soon require replacement. Given the vehicle’s age and low mileage, pay particular attention to time‑related items: inspect the 12 V battery for sulphation, check the electrolyte level if it is a conventional lead‑acid type, and confirm that the terminals are clean and tight. Examine the brake discs for surface rust or pitting, and ensure the calipers move freely without binding; any shudder or pulsation under braking would warrant a disc resurfacing or replacement. Verify that the engine oil, coolant, brake fluid and power‑steering fluid have been changed within the recommended service intervals – fluids can degrade even when the car is not driven much. Finally, look for any signs of corrosion on the chassis, exhaust hangers and under‑tray, especially if the car has been stored in a damp environment, and request a full service history to confirm that scheduled maintenance has been observed.
