A Gentian Blue Metallic 2025 Porsche 718 Spyder RS Weissach with just 1,100 miles on the clock is currently up for bid on Bring a Trailer, where the auction is set to close on September 1 out of Royal Oak, Michigan. As one of the last great naturally aspirated Boxsters, this Weissach-optioned example gives shoppers a rare shot at a barely-driven example of Porsche's screaming flat-six roadster.
Under the rear deck is Porsche's high-revving 4.0-liter flat-six, factory rated at 493 horsepower and 331 lb-ft of torque and mated to a seven-speed PDK dual-clutch transaxle. The drivetrain is backed by Porsche Torque Vectoring and a mechanical locking differential, while a sport exhaust system keeps that motorsport-bred engine vocal. This car's Weissach package layers on additional carbon-fiber exterior and interior trim atop a black soft top and 20-inch forged alloy wheels wrapped in Dunlop rubber, with braking handled by black-finished Porsche calipers over dimpled, ventilated rotors.
Inside, black leather and gray Race-Tex trim wrap carbon-fiber full bucket seats, a Race-Tex-covered steering wheel with a yellow center stripe, and a digital gauge cluster that spins to a 9,000-rpm redline alongside a 200-mph speedometer. Porsche Communication Management with navigation, dual-zone climate control, a backup camera, and rear parking sensors round out the equipment list on a car that still reads like it just left the showroom floor.
According to the listing, the car carries a clean Carfax with no accidents or damage reported, a single documented service visit, and an oil change performed this past April. Selling dealer 248Garage has it titled in Michigan, and bidding had reached $85,000 at the time of writing, a figure that leaves plenty of room to run before the lot closes.
That current bid looks especially light next to what Hagerty's valuation tools show for the model. Hagerty's price guide pegs a 2025 718 Spyder RS in #3, or good, condition at roughly $216,000, well above the car's original window sticker near $164,200. Hagerty's data also tracks a wide spread of recent public sales for the 718 Spyder RS and its GT4 RS sibling, from lows around $90,300 up to a $248,500 result for a 2025 Cayman GT4 RS Clubsport, with dozens of examples changing hands at auction over the past three years. Where this particular Weissach car lands between those extremes by September 1 will say a lot about how the market currently values a nearly new, low-mile example of Porsche's naturally aspirated send-off.
The Spyder RS's high-strung, naturally aspirated formula fits into a broader story of Porsche specials that keep gaining attention from collectors. Motorious recently looked at two rare Porsche 356s crossing the block at Gooding & Company's 2026 Pebble Beach auction, plus a matching-numbers 1958 Porsche 550A Spyder from the same sale, and a Le Mans class-winning Porsche 924 Carrera GTR with Brumos Racing history. Fans of Porsche's modern GT playbook may also want a look at this carbon-bodied Porsche 911 RT restomod built from a 911 GT3 RS, which chases a similarly high-revving ideal in a very different package.
With six days left on the clock, bidding on this 718 Spyder RS Weissach still has plenty of time to climb. For now, it stands as an interesting real-time data point on how much buyers are willing to pay for one of the last naturally aspirated Boxsters while it's still essentially new.
