The bottom line
A shiny Cayenne is a weak signal. Repaint shows up on 83% of these cars, so fresh paint should make you look harder, not easier, and a spotless dash is worse — codes get cleared here far more often than across the fleet, which matches the active electronic faults and HVAC glitches that keep appearing. Start at the engine: oil leaks hit two-thirds of the cars, with fuel trim out of range close behind. Cold-start it, scan it yourself, and negotiate or walk if a leak or stored fault will not be priced in. Structural repairs are uncommon, so a clean frame is not the win.
