1998 Mazda Bongo 2.5L Diesel · R602 ADP

The vehicle’s most recent MOT tests, conducted within a tight 18-day window in June 2025, reveal a concerning pattern of repeated failures despite identical mileage readings. The tester’s failure to record any defects—despite two consecutive re-tests at 132,577 miles—suggests either an administrative oversight or a vehicle that narrowly avoided serious mechanical failings. The previous cycle in May 2025 also ended in failure at 132,546 miles, reinforcing the impression of unresolved issues. While the 2024 tests show a similar pattern of a failed and passed test within days, the lack of specific defect codes makes it impossible to determine whether the vehicle was consistently close to failure or if the failures were arbitrary. The most recent pass in June 2025, however, means the vehicle has been legally roadworthy for just over a year, which is acceptable but not reassuring given the history. The recorded mileage of 132,577 miles over 21 years equates to an average of around 6,300 miles annually, a rate that aligns with typical usage for a vehicle of this age. There are no significant gaps in mileage between tests, and the progression is steady without abrupt jumps that might indicate deferred maintenance or extended periods of disuse. The only notable anomaly is the repeated failures at nearly identical mileages, which could imply the vehicle was driven to the test centre multiple times in quick succession—perhaps to bypass a genuine mechanical issue. This behaviour, if intentional, raises questions about the transparency of previous ownership. Given the lack of specific defect codes in the MOT history, a buyer should prioritise an independent inspection of high-wear components that commonly fail without obvious external signs. The repeated failures suggest potential issues with brakes, suspension, or exhaust emissions, though without test notes, it is impossible to confirm. Focus on the condition of brake discs and pads for uneven wear or glazing, suspension bushes for excessive play or cracking, and coil springs for corrosion or fatigue. Structural integrity should also be assessed, particularly around wheel arches, sills, and the subframe, as rust can compromise safety without being visible from the exterior. The absence of advisories in the record is unusual, so any noted issues should be treated as critical rather than minor.
