MAZDA B SERIES

Counts, not a score
1,493 passes · 548 fails
Snapshot generated 2026-08-24 from the compact derived MOT model summary. Duplicate MOT labels that share a URL slug were canonicalised to the higher-volume row. No per-test or per-VIN records are published.
Is a high MOT pass rate the same as reliability?
No. MOT tests a defined set of roadworthiness items at a point in time. They do not measure durability, crashworthiness, or US complaint volume. Sparse models (under 500 tests) are not published.
Are these UK or US figures?
UK. The rest of ModelYearFacts is US NHTSA and EPA evidence. This hub is Great Britain MOT statistics on the same nameplate, published under the Open Government Licence.
