MINI One: MOT pass rate and reliability data

The MINI One passes its MOT first time more often than the average UK car, by 8.1 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 49,483 individual MINI One tests. Nothing here is an estimate or a survey.

The numbers

First-time pass rate84.8%
UK national average76.7%
Difference+8.1 points
Tests analysed49,483
Average mileage at test56,580 miles
Average year of manufacture2015
Reliability rank1,252 of 2,005 models

What this means if you are buying one

A 84.8% first-time pass rate means roughly 15 in every 100 MINI Ones presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average MINI One tested had covered 56,580 miles and was built around 2015.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The MINI One sits 8.1 points above the national average, ranked 1,252 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific MINI One rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see the median recorded closing bid for a damaged MINI One: £500 at UK salvage auction, from 3 ended listings, not independently confirmed sales.

Most common MOT advisories on a MINI One

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a MINI One before it actually fails on it.

  1. A tyre seriously damaged, 21.8% of tests (1.41x the national rate for this advisory), also fails
  2. Tyre tread depth not in accordance with the requirements, 23.8% of tests, also fails
  3. Brake disc or drum excessively weakened, insecure or fractured, 9.2% of tests
  4. a brake lining or pad worn below 1.5mm, 7.9% of tests, also fails
  5. A suspension pin, bush or joint excessively worn, 4.1% of tests
  6. Brake disc or drum significantly and obviously worn, 3% of tests
  7. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 2.8% of tests
  8. A suspension component excessively damaged or corroded, 2.4% of tests
  9. Brake pipe damaged or excessively corroded, 2.1% of tests
  10. A spring or spring component fractured or seriously weakened, 2% of tests

From 48,865 DVSA-tracked MINI One tests, 2024.

MINI One pass rate by model year

From its 2008 to its 2021 model year, the MINI One's first-time pass rate has risen 31.2 points, from 61% to 92.2%, the usual pattern: a newer model year is a younger car today, so it fails less. First-time pass rate for each MINI One year:

MINI One by fuel type

The MINI One's two most-tested fuel types split by 2 points: petrol passes first time 85.3% of the time (43,768 tests) against 83.3% for diesel (5,506 tests).
