Is the BMW M3 reliable?

On MOT evidence the BMW M3 is well above average. It passes 88.3% of tests once age and mileage are accounted for, against a national average of 72.3%, which ranks it 7 of 262 models with enough data for a fair comparison. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What is the most common MOT failure on a BMW M3?

The item recorded most often is "A tyre cords visible or damaged", which appears in 15.5% of failed BMW M3 tests. Because one failed test can list several items, these shares do not add up to 100%.

What do testers most often warn about on a BMW M3?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 12.5% of all BMW M3 tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a BMW M3 usually have at its MOT?

The average odometer reading recorded at test is 75,413 miles. This is the mileage across all tested examples of every age, not an annual figure, so treat it as a description of the fleet rather than a target for one car.

Does a BMW M3 get harder to pass as it ages?

Yes. At 3 to 5 years old, 93.4% of BMW M3 tests pass. By fifteen years or more, that falls to 84.2%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Data updated 29 July 2026

Quick answer

The BMW M3 passes 88.3% of MOT tests once results are adjusted for the age and mileage of the cars tested, against a national average of 72.3%. That is well above average, ranking it 7 of 262 models with enough data to compare fairly. Based on 16,325 tests. Its most commonly recorded failure is tyre cords visible or damaged, which appears in 15.5% of failed tests. Cars of this model average 75,413 miles on the odometer when tested.

How this was worked out

Method and limits

Figures come from the DVSA anonymised MOT testing dataset, published under the Open Government Licence. Only class 4 initial tests are counted: retests are excluded so a car appears once, and abandoned tests are excluded entirely. The adjusted rate is directly standardised across twenty-five age and mileage bands and reweighted onto the national distribution, so this model is compared against cars that have lived a similar life rather than against a younger or lighter-used fleet.

An MOT measures whether a car met a legal standard on the day. It is not a breakdown record, a service history or a running-cost estimate, and a pass rate is a property of a fleet rather than a prediction about one car.
