How the BMW 520 holds up with age

Every car fails the MOT more often as it gets older. What matters when you are buying is how steeply that happens for this particular model. These are the 2025 pass rates for the BMW 520 grouped by the vehicle's age at the time of the test.

11 years and over45,93577.97%

The BMW 520 loses 9.1 percentage points between its early years and the 11-plus bracket — a normal pattern for a car of this age, but still worth checking the individual history.

What this means when buying a used BMW 520

A pass rate is a population average, not a verdict on the specific car in front of you. The average BMW 520 came to its 2025 test at 123,501 miles and 12.4 years old. Most examples tested were diesel.

The useful check is the individual car's own MOT record: how many times it has failed, what for, and whether advisories keep reappearing. A recurring advisory on corrosion, suspension or brakes tells you far more than a model-wide average, and a mileage that does not move consistently between tests is a warning in itself.
