2004 BMW 3 Series 2.5L Petrol · NB53 AED

The 2004 BMW 3 Series presents a clean and stable maintenance trend. The most recent MOT, conducted on 19 November 2025 at 120,906 miles, passed with zero defects. This marks the fifth consecutive advisory-free pass, indicating a resolving or consistently well-maintained condition with no recurring mechanical faults. The mileage accumulation tells a clear story of light, steady use. Between the October 2022 test at 94,606 miles and the November 2025 test at 120,906 miles, the vehicle covered approximately 26,300 miles over three years, averaging around 8,767 miles annually in its most recent period. This is a notable uptick from the earlier average of roughly 5,496 miles per year over its full lifespan. The jump suggests the vehicle has been used more regularly in recent years, which is generally positive for a diesel or petrol engine that benefits from regular running and avoids the issues associated with prolonged standing. Despite the clean MOT record, a buyer must still conduct a thorough physical inspection. A 22-year-old BMW 3 Series, even at low mileage, remains susceptible to age-related deterioration. Inspect the subframes, inner wing arches, and sill edges for corrosion, as structural rust can develop independently of mileage. Examine the condition of rubber suspension bushes and dust boots, which perish with age rather than mileage. The N46 and M47 engines of this era are known for timing chain and injector issues; listen for rattles on a cold start and check for excessive exhaust smoke. The clean MOT history is encouraging, but it does not substitute for a pre-purchase inspection by a specialist familiar with BMW's specific weak points.
