2023 Subaru Forester 2.5L Petrol · XNZ 20

The most recent MOT, carried out on 19 January 2026, was passed with no recorded defects, and the preceding test on 20 December 2024 also returned a clean result. This uninterrupted series of passes suggests a stable maintenance pattern and indicates that, at least at the time of the last two inspections, the vehicle’s essential safety and emissions items were in satisfactory condition. There is no evidence of a deteriorating trend, which is encouraging for a prospective buyer. At 95 229 miles on a 2005 model, the Forester averages roughly 4 500 miles per year – considerably below the typical UK usage for a vehicle of this age. The low annual mileage often points to light, possibly intermittent, use and may imply periods where the car has been stationary for extended stretches. While reduced wear on high‑stress components such as the engine, transmission and brakes is a benefit, prolonged storage can accelerate the ageing of rubber and polymer parts, promote corrosion on the under‑carriage, and lead to battery and fluid degradation that are not reflected in mileage alone. When inspecting a low‑mileage, lightly‑used Forester, start with the tyres. Verify tread depth is above the legal minimum, examine the sidewalls for cracking, dry‑rot or delamination, and check the DOT code to confirm the tyres are not older than six years, as ageing compounds can fail even with low wear. The 12‑volt battery should be tested for cranking voltage and checked for any signs of sulfation or leaking electrolyte; a battery that has sat idle for years often requires replacement even if the charge appears acceptable. All primary fluids – engine oil, coolant, brake fluid and power‑steering fluid – should be inspected for colour, clarity and level, and any fluid that has not been changed within the manufacturer’s two‑year interval should be flushed and refilled, as time‑based breakdown can lead to reduced lubrication and corrosion. Finally, examine the suspension and steering components for dry‑rot in the rubber bushes, cracked coil‑spring mounts and any play in the ball joints or tie‑rod ends, as these elements can deteriorate with age regardless of mileage. The brake discs should be lifted to assess surface rust and thickness; surface rust is common on infrequently used cars but deep pitting or uneven wear may indicate a sticking caliper that will need cleaning or rebuild. The Subaru’s timing belt, typically scheduled for replacement around 100 000 miles or every 7‑8 years, is approaching its service interval and should be inspected for wear or replaced as a precaution to avoid catastrophic engine damage. A thorough visual under‑carriage inspection for rust, especially around the wheel arches, sills and exhaust system, will also help confirm that the vehicle has been stored in a dry environment and has not suffered structural corrosion.
