The 4.6 V8 is robust; the 6.8 kWh lithium-ion traction battery is the defining ownership question: packs age with time and charging discipline as much as mileage, replacement runs from roughly $50,000 to $125,000 or more through Porsche Classic, and documented battery health — or a completed factory replacement — now features in the provenance of the best cars. A Porsche battery state-of-health report should be considered non-negotiable at purchase. High-voltage battery service intervals, cooling and electronics are the dominant ownership variables. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history, leak-down or compression testing where appropriate, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.
