How the BMW 420 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 420 grouped by the vehicle's age at the time of the test.
| Age at test | Tests | Pass rate |
|---|---|---|
| 3–5 years | 3,410 | 88.15% |
| 6–10 years | 50,066 | 85.31% |
| 11 years and over | 8,111 | 78.86% |
The BMW 420 loses 9.3 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 420
A pass rate is a population average, not a verdict on the specific car in front of you. The average BMW 420 came to its 2025 test at 73,673 miles and 8.3 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.
