The bottom line
These Cayennes come with a lot of paint work already done and codes that have been cleared, so treat the history as incomplete. The engine is the weak spot—oil leaks are the first thing to hunt for on a cold morning, followed by a proper scan for the active error codes and fuel-trim problems that keep appearing. Check the HVAC electronics and tire wear next. No structural repairs is reassuring, but if you find fresh leaks or more hidden codes, walk or negotiate hard because those issues will not stay cheap.
