MINI Cooper S: MOT pass rate and reliability data

The MINI Cooper S passes its MOT first time more often than the average UK car, by 11.4 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 86,798 individual MINI Cooper S tests. Nothing here is an estimate or a survey.

What this means if you are buying one

A 88.1% first-time pass rate means roughly 12 in every 100 MINI Cooper S 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 Cooper S tested had covered 41,185 miles and was built around 2017.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a MINI Cooper S bought as a 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 Cooper S 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 what damaged MINI Cooper S actually sold for at UK salvage auction.

  10. The aim of a headlamp is not within limits laid down in the requirements, 0.3% of tests

From 159,577 DVSA-tracked MINI Cooper S tests, 2024. DVSA testers marked 6.48% of these flagged MINI Cooper S defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 4.97% nationally.

MINI Cooper S pass rate by model year

Pass rates fall steadily as cars age, so the model year matters as much as the model. First-time pass rate for each MINI Cooper S year:

Diesel and petrol versions of the same car fail on different things, so the fuel type moves the number:
