2000 Mazda 323 — MOT failures & pass rate
The 2000 Mazda 323 passed 71.5% of its 1,184 recorded MOT tests. All cars of a similar age fail 26.8% of the time, so this is 1.7pp worse than the group it competes with. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (15.5%) and lighting & signalling (14.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, headlamp aim and headlamp — component mounting prescribed areas alone was recorded 150 times.
A 150k+ example is materially riskier than a 0-30k one: 27.5% versus 8.6%.
Advisories point at the next bill rather than this one: suspension was flagged on 48.9% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 48.9% | 579 |
| 2 | Brakes | 31.9% | 378 |
| 3 | Tyres | 31.8% | 376 |
| 4 | Lighting & signalling | 16.3% | 193 |
| 5 | Body, structure & corrosion | 16.1% | 191 |
| 6 | Other defects | 15.3% | 181 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 35 | 8.6% |
| 30-60k | 252 | 23.8% |
| 60-90k | 443 | 30.9% |
| 90-120k | 278 | 29.9% |
| 120-150k | 132 | 33.3% |
| 150k+ | 40 | 27.5% |

What to check before buying a 2000 323
On a 2000 323, suspension is what the MOT record says goes wrong most — it appeared in 15.5% of tests. Check these areas before you commit.
- Suspension (15.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Lighting & signalling (14.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (10.6% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
