The bottom line
High repaint rates paired with oil leaks in 73% of these Cayennes and frequent active error codes paint a clear picture: cosmetics and electronics get patched while the engine quietly weeps. Skip the shiny exterior and go straight for a lift inspection—look for seepage around the engine and demand a live scan that hasn't been wiped, because cleared codes pop up often enough to raise flags. Tires and HVAC electronics add nickel-and-dime hits. The absence of structural repairs is reassuring, so focus negotiation on documented leaks or fresh paint jobs; walk away from any seller who won't let you verify the underbody yourself.
