Truffle Brown Club leather, the Sweetgum Interior Package, PDCC Sport, rear axle steering, and Night Vision Assist all feature across 49,200 miles. Bidding stands at $43,000 with five days remaining and ten bids placed.2018 Porsche Panamera 4S Sport TurismoCars & BidsWhat it's worth right nowData from Kelley Blue Book sets the 2018 Panamera 4S Sport Turismo resale value at $41,700, with private party figures from $39,180 to $43,780 and trade-in from $38,180 to $42,780. Retail listings for a 2018 4S showing 99,654 miles sit at $36,900.AdvertisementAdvertisementBoth benchmarks assume ordinary mileage and ordinary specification, and this car is neither. Half the miles of that retail comp plus PDCC Sport, rear axle steering, Night Vision Assist, and the Sweetgum package argue above the published numbers, while two paint repairs and a replaced intake manifold argue back. Fair value lands between $46,000 and $58,000, with $51,000 most likely. The current bid of $43,000 carries ten bids and five days against a reserve.2018 Porsche Panamera 4S Sport TurismoCars & BidsCondition and detailsThe option sheet is the story. Beyond Premium Package Plus and the SportDesign Package in high gloss black sit 21-inch Exclusive Design wheels, PDCC Sport active anti-roll control, rear axle steering, a panoramic sunroof, Club leather in Truffle Brown, the Sweetgum Interior Package, four-zone climate control, front and rear ParkAssist with Surround View, and Night Vision Assist. The seller adds an iPE valvetronic exhaust, yellow calipers, window tint, and a ceramic coating, and retains the factory exhaust in storage.2018 Porsche Panamera 4S Sport TurismoCars & BidsTwo Carfax entries need explaining, and the seller does explain them. Minor damage to the left front in October 2023 came from a parking garage swipe that gouged a fender and required a new OEM wheel, while minor damage to the right side in September 2024 happened when the seller caught the rear passenger fender entering a garage. Both panels were repainted at shops the seller describes as Porsche-recommended. Exterior chips and seat creasing are also disclosed.2018 Porsche Panamera 4S Sport TurismoCars & BidsMechanical history carries two flags worth pricing. An intake manifold was replaced in December 2022 at 31,852 miles and the cooling system was serviced in May 2023, both meaningful entries on a twin-turbo V6. The seller also notes the iPE exhaust may prevent the car passing emissions in some states, which a California buyer in particular should resolve first. A pre-purchase inspection from a Porsche specialist should cover the air suspension, PDCC, and a full fault-code history.2018 Porsche Panamera 4S Sport TurismoCars & BidsAdvertisementAdvertisementThe offerSpecificationDetailMakePorscheModelPanamera 4S Sport TurismoYear2018Mileage49,200 milesEngineTwin-turbocharged 2.9-liter V6Power440 horsepower and 405 lb-ft of torqueTransmissionEight-speed PDK dual-clutch automaticDrive typeAll wheel driveExterior colorGT Silver MetallicInterior colorTruffle BrownCurrent bid$43,000 with five days remainingInterested in this car? View the listing here.What makes the Panamera Sport Turismo uniqueSceptics went quiet when the second-generation Panamera arrived. Launched for 2017 on an aluminum-intensive architecture with a sleeker roofline than the original, it fixed the styling complaints that had trailed the car since 2009, and the Sport Turismo that followed in 2018 became the first series-produced station wagon in Porsche's history. The 2.9-liter twin-turbo V6 in 4S form makes 440 horsepower, which is plenty for something that also swallows luggage.Depreciation now does the interesting work. A Sport Turismo that cost well past $120,000 with options trades in the $40,000 range, which buys air suspension, rear axle steering, and PDCC for the price of a mid-trim crossover. Production ended in 2024 with no direct wagon replacement in the range, so the body style is finite, and the enthusiast option boxes on cars like this one are the ones the market has started noticing.My takeAt $43,000 with ten bids and five days to run, my call is $51,000, with $58,000 possible if two buyers recognize how rarely PDCC Sport, rear axle steering, and Night Vision Assist appear together on a wagon. The specification carries the whole argument, since Truffle Brown over GT Silver with the Sweetgum package is a combination nobody orders by accident and the enthusiast hardware is all present. What tempers it is a Carfax with two paint repairs, both credibly explained but permanent on the record, plus an intake manifold replaced at 31,852 miles and an exhaust that may complicate registration. Get the specialist inspection, ask for the repair invoices, and negotiate the factory exhaust into the deal.AdvertisementAdvertisementDisclaimer: This post is for informational purposes only.
