It sits on Bring a Trailer at $400,000 with six days to go.2025 Porsche 911 GT3 RSBring a TrailerWhat it's worth right nowThe GT3 RS, particularly with the Weissach and Manthey packages, commands serious money. According to Classic.com and recent sales, 992 GT3 RS examples generally trade from the low $300,000s past $400,000, with Weissach cars and the expensive Manthey Racing kit pushing well into the upper part of that range and beyond.AdvertisementAdvertisementThe Weissach and Manthey packages and low mileage support the value, tempered by the history. A Manthey-kitted Weissach RS is exactly what collectors want, but the ex-marketing status and title situation are factors. Fair value lands at $380,000 to $480,000, with $425,000 the most likely close.2025 Porsche 911 GT3 RSBring a TrailerCondition and detailsThe specification is the pinnacle. Finished in black, it carries the Weissach Package, which adds a carbon roof, front lid, anti-roll bars, and interior trim to save weight, and the dealer-installed Manthey Racing kit, which brings revised aero, semi-active coilovers, braided brake lines, and rear-wheel aerodiscs.2025 Porsche 911 GT3 RSBring a TrailerThe engine and hardware are extraordinary. The naturally aspirated 4.0-liter flat-six produces 518 horsepower and revs to a 9,000-rpm redline, driving the rear wheels through a seven-speed PDK, backed by carbon-ceramic brakes, rear-axle steering, magnesium center-lock wheels, and active aerodynamics with a drag-reduction system.2025 Porsche 911 GT3 RSBring a TrailerThe history and status warrant real attention. The car was a Porsche marketing and track-use vehicle before the dealer acquired it, so it has seen some track mileage, it received Porsche Approved certification, and it does not have a title, being sold on its Manufacturer's Certificate of Origin with the dealer assisting registration.2025 Porsche 911 GT3 RSBring a TrailerAdvertisementAdvertisementThe offerSpecificationDetailMakePorscheModel911 GT3 RSYear2025Mileage3,600 milesEngine4.0-liter flat-sixPower518 hp and 342 lb.ft of torqueTransmission7-speed PDK dual-clutch automaticDrive typeRear-wheel driveExterior colorBlackInterior colorBlackCurrent bid$400,000, with six days leftInterested in this 2025 Porsche 911 GT3 RS? View the listing here.What makes the GT3 RS uniqueThe 992 GT3 RS is the most extreme naturally aspirated 911 Porsche has ever built for the road, a car engineered for aerodynamics to a degree never seen before on a street car. Its enormous swan-neck rear wing, active DRS, and countless underbody and bodywork elements generate massive downforce, while the screaming 4.0-liter flat-six, carbon-ceramic brakes, and center-lock magnesium wheels give it genuine race-car capability. It is a road-legal track weapon that blurs the line between showroom and paddock.2025 Porsche 911 GT3 RSBring a TrailerThe Weissach Package and Manthey Racing kit take that already-extreme machine even further. The Weissach option strips weight with carbon components, while the Manthey kit, developed by Porsche's own motorsport partner, adds still more downforce and adjustability. That combination of the most hardcore factory RS, the weight-saving Weissach Package, and the coveted Manthey performance kit is exactly what makes this GT3 RS such a special and desirable track-focused machine.My takeThis is a track-focused, ultra-capable, and superbly-specified GT3 RS, and the appeal is the combination of the Weissach Package and the coveted Manthey Racing kit. The screaming flat-six, the extreme active aerodynamics, the weight-saving carbon, and the Manthey downforce upgrades make it a genuine road-legal track weapon, and few street 911s get more extreme.AdvertisementAdvertisementFair value sits at $380,000 to $480,000, with $425,000 the most likely result, and the crux is the ex-marketing history and title status rather than the car's staggering capability. Before bidding, review the track-use history and the Porsche Approved certification, understand it is sold on a Manufacturer's Certificate of Origin rather than a title, and confirm the registration path for the buyer's state. Handle that, and this is one of the most capable and desirable street 911s ever built.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
