How reliable are Minis really? We analysed 795,995 real MOT tests from the DVSA database to find out which Mini models pass most often and which years are worth buying.
This isn't survey data or owner opinions. These are actual pass/fail results from UK garages, covering Mini models sold in the UK from 2000 to 2023.

The COUNTRYMAN leads Mini's lineup with an 85.8% pass rate.
Proven Durability Champions: Which Mini Models Age Best?
These Mini models show solid long-term reliability based on 11+ years of MOT data. Here's how they compare to the national average for cars of the same age:
High-confidence data: Only vehicles with 11+ years of MOT history and 100+ tests are included in this ranking.
| Model | Year | Fuel | vs Same-Age Average | Tested At | Pass Rate |
|---|---|---|---|---|---|
| PACEMAN | - | All | +15.7% | 11-14 years | 80.3% |
| JOHN COOPER WORKS | - | All | +14.8% | 11-14 years | 79.5% |
| COUNTRYMAN | - | All | +11.6% | 11-14 years | 76.2% |
| FIRST | - | All | +10.2% | 11-14 years | 74.8% |
| COOPER | - | All | +9.2% | 11-14 years | 73.8% |
| ONE | - | All | +8.7% | 11-14 years | 73.3% |
| MINI | - | All | +7.7% | 11-14 years | 72.4% |
| COOPER | - | All | +4.2% | 15-17 years | 62.0% |
| MINI | - | All | +2.5% | 15-17 years | 60.4% |
How to read this: A score of "+15%" means the model passes MOTs 15 percentage points more often than the average car of the same age. These are proven results from vehicles that have genuinely aged well.
Proven durability champion
The PACEMAN outperforms the average 11-14 years-old car by 16 percentage points, with 661 MOT tests proving its reliability.
Early Performers: Strong Start, Unproven Durability
These newer Mini models (3-6 years old) show strong early results, but haven't yet proven long-term durability:
Important caveat: Durability NOT yet proven - too early to assess long-term reliability. Older versions of the same model may tell a different story at 11+ years.
| Model | Year | Fuel | vs Same-Age Average | Tested At | Pass Rate |
|---|---|---|---|---|---|
| PACEMAN | - | All | +9.3% | 8-10 years | 84.7% |
| COUNTRYMAN | - | All | +8.4% | 8-10 years | 83.8% |
| COOPER | - | All | +8.2% | 8-10 years | 83.6% |
| ONE | - | All | +7.8% | 8-10 years | 83.2% |
| JOHN COOPER WORKS | - | All | +7.5% | 8-10 years | 83.0% |
| MINI | - | All | +7.4% | 8-10 years | 82.8% |
| UNCLASSIFIED | - | All | +7.2% | 8-10 years | 82.6% |
| CLUBMAN | - | All | +6.4% | 8-10 years | 81.9% |
What this means: These models are performing well in their early years, but we recommend checking the Durability Champions section above to see how older versions of the same model family have fared over time.

Mini Hybrids vs Petrol vs Diesel
Reliability varies by fuel type for Mini. Here's how each performs:
| Fuel Type | Average Pass Rate | vs National | Tests |
|---|---|---|---|
| Electric | 88.8% | +17.4% | 3,485 |
| Hybrid Electric | 87.1% | +15.7% | 9,263 |
| Diesel | 76.0% | +4.5% | 149,839 |
| Petrol | 75.9% | +4.4% | 633,397 |
The hybrid advantage: Mini hybrids pass MOTs 11% more often than petrols and 11% more often than diesels.
Mini Models to Avoid
Not all Minis are reliable. These specific model/year combinations have failure rates well above average:
| Model | Year | Fuel | Pass Rate | Tests |
|---|---|---|---|---|
| MINI | 2001 | Petrol | 46.6% | 2,521 |
| MINI | 2002 | Petrol | 51.1% | 10,141 |
| MINI | 2005 | Diesel | 50.4% | 605 |
| MINI | 2003 | Petrol | 53.6% | 14,952 |
| MINI | 2004 | Petrol | 54.1% | 20,477 |
| COOPER | 2007 | Petrol | 56.0% | 727 |
| MINI | 2005 | Petrol | 55.6% | 24,622 |
| MINI | 2006 | Petrol | 55.9% | 23,147 |
| MINI | 2007 | Petrol | 57.2% | 26,391 |
| MINI | 2007 | Diesel | 58.3% | 2,608 |
Pattern to avoid
Early 2001-2007 diesel/petrol MINIs are the models that drag down Mini's average. The MINI performs 9% worse than the average car of the same age at 21+ years - this is proven poor durability. These vehicles fail MOTs more often than they pass.
What Goes Wrong on Minis?
When Minis fail MOTs, these are the most common causes:
| Failure Category | Total Failures |
|---|---|
| 1. Lamps, reflectors and electrical equipment | 76,744 |
| 2. Tyres | 48,198 |
| 3. Brakes | 40,173 |
| 4. Visibility | 36,019 |
| 5. Suspension | 31,858 |
| 6. Noise, emissions and leaks | 29,884 |

Pre-MOT checklist for Mini owners:
- Check all bulbs (number plate lights are commonly missed)
- Ensure tyres meet 1.6mm tread requirement
- Check brake pad thickness and disc condition
- Clean windscreen and check wiper blade condition
- Inspect suspension bushes and anti-roll bar links

About This Data
This analysis uses real MOT test results from the DVSA database, covering 795,995 tests on Mini vehicles between 2000 and 2023.
Year-Adjusted Scoring (v2.1): In year-by-year breakdowns, each vehicle is compared against the national average for vehicles of the same model year. This removes the natural bias where newer cars pass more often, allowing fair comparisons across eras.
Evidence-Tiered Durability: We separate "proven durability" (vehicles tested at 11+ years old) from "early performers" (3-6 years old). Only vehicles with proven long-term data are used for durability claims. Age-band comparisons use weighted national averages.
Minimum thresholds: 100 tests for proven durability rankings, 100 tests for early performer rankings. Pass rates are calculated as first-time passes, excluding retests.
The overall national average MOT pass rate is 71.44% based on 32,300,000 tests across all manufacturers. Year-specific averages range from ~59% (2009 vehicles) to ~88% (2020 vehicles).
