What this means if you are buying one
Use it as a viewing checklist. If you are looking at a Porsche Cayenne, these are the areas worth inspecting and worth asking about — and worth reading the car's own MOT history for, since a defect that keeps reappearing as an advisory is a better signal than any model-wide average.
The MOT record also has hard limits: it does not check the engine, clutch or gearbox, and it says nothing about outstanding finance, insurance write-off history, stolen markers or whether the mileage is genuine. Our used Porsche Cayenne buying guide covers what to check beyond the MOT.
