The Mazda 323 Executive has an overall MOT pass rate of 63.2% across 2,225 real MOT tests — below the UK average, so reliability should be a key concern.
The most common problems on the Mazda 323 Executive are tyre tread depth below requirements of 1.6mm (210 recorded failures), registration plate lamp not working (190), and brake pipe excessively corroded (183). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
A typical Mazda 323 Executive owner drives around 7,396 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
In terms of longevity, most Mazda 323 Executive models stay on UK roads for around 30 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
