MOT pass rate · 2025 data
Porsche Cayman MOT pass rate

How the Porsche Cayman 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 Porsche Cayman grouped by the vehicle's age at the time of the test.
| Age at test | Tests | Pass rate |
|---|---|---|
| 3–5 years | 1,359 | 96.03% |
| 6–10 years | 5,171 | 94.55% |
| 11 years and over | 7,745 | 86.96% |
The Porsche Cayman 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.
Why the Porsche Cayman fails its MOT
Across every Porsche Cayman that failed its 2025 MOT, the most common area of failure was brakes, accounting for 20.98% of all recorded failure items. These are the areas worth having checked before you buy, and worth budgeting for on an older example.
| Failure area | Share of failure items | Recorded items |
|---|---|---|
| Brakes | 20.98% | 589 |
| Lamps, reflectors and electrical equipment | 20.19% | 567 |
| Tyres | 19.55% | 549 |
| Suspension | 12.93% | 363 |

What this means when buying a used Porsche Cayman
A pass rate is a population average, not a verdict on the specific car in front of you. The average Porsche Cayman came to its 2025 test at 50,572 miles and 11.7 years old. Most examples tested were petrol.
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.
