The bottom line
Start under the hood, not at the paint. Oil leaks are the rule on these Cayennes, so put it on a lift and look for wetness before you even turn the key. Then scan it yourself—cleared codes show up far more often than on the typical used car, so a blank dash proves nothing. HVAC electronics and tired tires are the next things to poke. If you find active leaks or live faults, walk away. A dry engine and a quiet scan still leave the heavy repaint rate as a reason to knock the price down, not a reason to trust the car.
