2005 Subaru Forester 2.5L Petrol · NM55 MDX

The 2005 Subaru Forester presents a stable and reassuring maintenance trend, culminating in a completely clean pass on 28 November 2025 at 156,057 miles with zero defects recorded. This is not an isolated result. The vehicle has passed its last four consecutive MOTs without a single advisory or failure, indicating consistent mechanical care and a resolving or entirely absent pattern of recurring faults. For a vehicle of this age, a four-year stretch of defect-free testing is a strong indicator of diligent preventative upkeep rather than reactive repairs. The mileage accumulation is remarkably consistent and typical for a 21-year-old vehicle, averaging approximately 7,431 miles per year. Looking at the intervals between tests, the vehicle covered 373 miles between the November 2025 and December 2024 tests, 2,143 miles between December 2024 and September 2023, and 3,553 miles between September 2023 and September 2022. The most recent annual mileage is notably low, suggesting the vehicle may be seeing lighter use or shorter journeys in its current ownership. No significant gaps or suspicious jumps in the odometer record are present, and the data is clean and continuous. Despite the clean MOT record, the advisory notes from the 2022 and 2021 tests flag that the vehicle was covered in underseal. While underseal application is a proactive measure against corrosion, it can also mask underlying structural rust, particularly on a 20-year-old chassis. A buyer should thoroughly inspect the underside, sills, subframes, and suspension mounting points for any signs of hidden corrosion or deteriorating sealant. The boxer engine and symmetrical all-wheel-drive drivetrain should be checked for oil leaks, particularly from cam covers and rear main seals, which are common age-related issues on these engines. Given the clean recent history, the primary focus for any in-person inspection should be on the structural integrity of the chassis and the condition of consumable components that do not always trigger an MOT advisory until they are critically worn. Pay close attention to suspension bushes, coil springs, and drop links, as well as the condition of brake discs and pads, which may be approaching replacement if the recent low mileage consists of short trips that accelerate corrosion rather than wear. The clean MOT record is a positive foundation, but the vehicle's age demands a careful physical inspection to confirm that the underseal is still protecting sound metal rather than concealing deterioration.
