The Porsche 718 Spyder RS is the most extreme and powerful Boxster ever made, and one of the last of the great naturally aspirated open-top Porsches. This 2025 example is a near-new, loaded Weissach car in Guards Red. It sits on Cars and Bids at $178,000 with five days to go.

What it’s worth right now
The 718 Spyder RS has settled from its initial above-sticker frenzy but remains strong. According to Classic.com and recent data, the Spyder RS carries a market benchmark close to $198,000, with the range running from close to $120,000 into the $400,000s for the very best cars, and recent auction results trending below the earlier peak.
The near-new condition and loaded spec support the value, tempered by a cooling market. A barely-driven Weissach car in a desirable color is exactly what buyers want, but values have softened from the launch frenzy. Fair value lands at $165,000 to $205,000, with $190,000 the most likely close.

Condition and details
The specification is the draw. Finished in Guards Red over black, it carries the coveted Weissach Package, 20-inch forged magnesium wheels, Porsche Ceramic Composite Brakes, Race-Tex upholstery, and a Guards Red stopwatch dial, with more than $41,000 in options on a $217,545 sticker, and it shows just 600 miles.

The break-in status warrants attention. As one commenter noted, Porsche specifies a careful break-in procedure for this GT3-derived engine, and at 600 miles the car is not yet fully broken in, so it will need a further service, which is worth factoring in.

The engine is the whole point. The 718 Spyder RS shares its high-revving, naturally aspirated 4.0-liter flat-six with the Cayman GT4 RS and the 992 GT3, a motorsport-derived unit that is genuinely one of the last of its kind as Porsche electrifies the 718 line.

What makes the 718 Spyder RS unique
The 718 Spyder RS represents the glorious high point of the mid-engined Boxster, the most powerful and focused version Porsche ever built. It shares its core hardware with the track-focused Cayman GT4 RS, including the screaming, naturally aspirated 4.0-liter flat-six derived from the 992 GT3 and a short-ratio dual-clutch transmission, but pairs it with a lighter, open-top body and a bespoke chassis setup. The result is a raw, visceral, and utterly intoxicating driving experience, with a wailing 9,000-rpm engine positioned right behind the driver’s head and minimal sound deadening to let every note through.
Cars & Bids
That combination of a motorsport-derived engine, open-air drama, and razor-sharp dynamics is exactly what makes the 718 Spyder RS so special, and so significant. As Porsche prepares to electrify the 718 line, this car stands as one of the last naturally aspirated, flat-six, open-top Porsches, a genuine sending-off of a beloved formula, which is why low-mileage examples like this one are so coveted by collectors and enthusiasts alike.
My take
This is a genuinely special and significant Porsche, and the appeal is a near-new example of one of the last great naturally aspirated open-top Porsches. The GT3-derived flat-six, the loaded Weissach specification, and the desirable Guards Red finish make it a standout, and its status as a last-of-its-kind car underpins its long-term desirability.
Fair value sits at $165,000 to $205,000, with $190,000 the most likely result, and the crux is the cooling market and the break-in service rather than anything to do with the car itself. Before bidding, note that values have softened from the launch frenzy, budget for the post-break-in service, and get a pre-purchase inspection. Handle that, and this is a barely-driven example of a modern Porsche icon.
