Buying a used Porsche Cayenne
The Porsche Cayenne passed 87.68% of its 29,877 initial MOT tests in 2025 — better than the 77.3% average for all cars. That tells you about the model. It tells you nothing about the specific car you are looking at, which is where the expensive surprises live.

What the MOT data shows about the Porsche Cayenne
Ranked on pass rate, the Porsche Cayenne sits 162 of 651 models in this data. Porsche as a marque averaged 89.3%, so this model runs 1.6 points behind its own brand. A pass rate is not a reliability score — it records whether cars met the roadworthiness standard on test day.
How age affects a used Porsche Cayenne
This matters more than the headline figure when you are buying: it shows what happens to this model as it gets older.
| Age at test | Tests | Pass rate |
|---|---|---|
| 3–5 years | 5,184 | 93.4% |
| 6–10 years | 11,778 | 89.89% |
| 11 years and over | 12,819 | 83.29% |
The Porsche Cayenne loses 10.1 percentage points by the 11-plus bracket — an ordinary decline, but enough that an older example deserves a proper look at its own MOT record.

What the MOT record will not tell you
Knowing that Porsche Cayenne failures cluster around tyres and lamps, reflectors and electrical equipment tells you what to inspect. It tells you nothing about whether the car is legally safe to buy. An MOT records that a car met a minimum standard on the day it was tested. It does not check the engine, clutch or gearbox, and it says nothing at all about the car's legal and financial history. On a 10.4-year-old average example those are the risks that cost real money:
- Outstanding finance. If money is still owed against the car, the lender may retain an interest in it after you have paid the seller.
- Insurance write-off history. A recorded Cat S or Cat N marker is permanent and affects safety, insurance and resale — and it does not appear on the V5C.
- Stolen markers. A vehicle recorded as stolen can be seized even from a buyer who bought it in good faith.
- Mileage history. Recorded readings that do not move consistently between tests are the clearest sign of a clocked car.
- Previous keepers. An unusual number of owners for the age of the car is worth asking about.
A Carpeep car history check reports all of those against the registration, plus tax status, import and export markers, scrapped status and the vehicle identity details, in one £15 report.

Used Porsche Cayenne FAQs
What should I check before buying a used Porsche Cayenne?
Check the individual car rather than the model: outstanding finance, insurance write-off records, stolen markers, mileage history and the number of previous keepers. None of these appear on the V5C or in the MOT record, and a seller does not have to volunteer them. On the model itself, DVSA data for 2025 shows the Porsche Cayenne passed 87.68% of its initial MOT tests.
Is the Porsche Cayenne reliable?
MOT data does not measure reliability, it measures whether a car met the roadworthiness standard on the day of its test. What it does show for the Porsche Cayenne is a 87.68% first-time pass rate across 29,877 tests in 2025, which is better than the 77.3% average for all cars.
