The bottom line
The Cayenne's story is an engine that weeps oil and a dashboard that likes to hide problems. Oil leaks show up on most of these, so get under it with a light before you even talk money, and treat a clean scan as suspicious because sellers wipe codes far more often than the rest of the used market. Expect HVAC electronics and fuel-trim issues to pile on, and assume most panels have been resprayed even if the structure is intact. Use the leaks and any live codes to negotiate hard, and walk if the oil is more than seepage or the codes come back after a reset.
