1997 Mazda Bongo 2.5L Diesel · P150 BHG

The most recent DVSA examination on 28 March 2025 resulted in a pass, though four advisories were issued. Three of these relate to corrosion of integral body structures on the nearside front inner, nearside rear outer sill, and offside outer sill, each noted as not yet significantly reducing structural rigidity. The fourth advisory records the offside rear tyre as worn close to the legal limit and worn on edge. Looking across the available MOT history, the maintenance trend has clearly worsened in recent years. Prior to 2020, the vehicle passed tests with either no defects or only minor advisories such as brake pad wear in 2019. Since then, two outright failures have occurred, in September 2020 and October 2021, with the most recent test now carrying multiple corrosion advisories. This trajectory indicates progressive structural deterioration that warrants close attention. With 182,097 miles recorded over approximately 18 years, this Mazda Bongo has averaged around 10,116 miles annually, which is broadly typical for its age and consistent with a working or leisure-use light commercial. The mileage progression between MOTs appears steady and uninterrupted, suggesting the vehicle has been in regular service rather than left standing for prolonged periods. This kind of consistent usage is generally favourable for mechanical components, as it reduces the risks associated with corrosion through inactivity and seized brakes from infrequent movement. However, the cumulative mileage itself places considerable wear on suspension, braking, and drivetrain components that will inevitably require attention at this stage of life. Given the recurring advisories relating to corrosion of integral body structures, particularly around suspension mounting areas and inner sills, any prospective buyer should arrange for the vehicle to be inspected on a lift to assess the extent of structural corrosion beyond what is visible from underneath. The advisories from the 2022 test regarding slight play in the nearside front anti-roll bar ball joint and D bushes, combined with the 2021 failure for an excessively worn anti-roll bar linkage ball joint, suggest ongoing wear within the front suspension. On a test drive, listen for clonks or knocks over uneven surfaces, pay attention to any vagueness or knocking through the steering, and check for uneven tyre wear across both axles. The offside rear tyre advisory from the latest test should be acted upon immediately, and all four tyres should be examined for age-related sidewall cracking given the vehicle's longevity. Beyond the documented MOT concerns, a vehicle of this age and mileage warrants thorough inspection of items that deteriorate with calendar age rather than mileage alone. The 12V battery should be load-tested, as prolonged standing and repeated short trips reduce its service life. Brake calipers and rear drums should be checked for seizing, a common issue on older commercial vehicles that can cause uneven braking or pulling to one side. All fluids, including engine oil, coolant, brake fluid, and if applicable transmission fluid, should be inspected for condition and service history, as brake fluid in particular absorbs moisture over time and should be renewed regardless of mileage. Finally, verify the timing belt replacement history if applicable to the engine variant, confirm the exhaust system for signs of corrosion or blowing, and ensure the service book contains evidence of regular maintenance, as a well-documented history on a high-mileage 18-year-old vehicle provides valuable reassurance.
