Just 1,948 were built worldwide, and this low-mileage example carries the desirable carbon and Heritage details. As one of the last analog, open-top driver's Porsches, it sits in rarefied and closely watched territory, so the number here matters.2019 Porsche 911 SpeedsterBring a TrailerWhat it's worth right nowClassic.com shows a Market Benchmark around $426,501 for the 991 Speedster, reflecting how firmly these limited, naturally aspirated, manual cars have held their value. The best low-mileage examples and Heritage Design cars sit at the top of that market, while higher-mileage cars trade somewhat below the benchmark. Dealer asking prices have ranged higher still, with individual cars advertised in the high-$400,000s.AdvertisementAdvertisementThis car's low mileage and specification place it toward the stronger part of the market. Speedsters were expensive when new, with a base price around $275,000 before options, and the limited build combined with the GT3 mechanicals has kept demand robust. The manual-only format is a plus in a market that increasingly prizes three pedals.2019 Porsche 911 SpeedsterBring a TrailerGiven the benchmark and this car's mileage and options, I would call fair value roughly $400,000 to $460,000. Because this is a blue-chip modern collectible, the final number will hinge on exact spec, condition, and how two committed bidders value the Heritage details and the preservation.Condition and detailsThe specification is the story on a car like this. It pairs the GT3's 502-horsepower 4.0-liter flat-six with a six-speed manual, and the Speedster adds its signature cut-down windshield, manually operated top, and the double-bubble rear tonneau cover. This example carries carbon-fiber elements and the Heritage Design cues that many buyers specifically seek, and the low mileage suggests a car that has been preserved rather than used up. As with any preservation-focused collectible, the priority is confirming that low use has been paired with proper maintenance rather than simply sitting.2019 Porsche 911 SpeedsterBring a TrailerThe mechanical diligence is straightforward but essential. On a GT3-derived engine, confirm the oil-service history and that fluids and consumables have been kept current despite the low mileage, and factor in tire age, since preservation-grade cars often wear rubber that is older than its tread depth suggests. A Porsche specialist inspection is worthwhile even on a nearly new car, both to verify condition and to confirm the service record supports the preservation premium.2019 Porsche 911 SpeedsterBring a TrailerThe documentation and provenance are what protect value here. Confirm the car comes with its books, tools, both tops or covers as delivered, and a clean history, and verify the build details against the options list. On limited Porsches like this, completeness and a clean story are worth real money, and any gaps should be reflected in the price.2019 Porsche 911 SpeedsterBring a TrailerAdvertisementAdvertisementThe offerSpecificationDetailMakePorscheModel911 Speedster (991.2)Year2019Mileage~1,900Engine4.0-liter flat-sixPower502 horsepower, 346 lb-ftTransmissionSix-speed manualDrive typeRear-wheel driveExterior colorWhiteInterior colorBlack leatherCurrent bidAuction liveInterested in this car?

That means the naturally aspirated 4.0-liter flat-six, a six-speed manual, and GT3 chassis hardware, all beneath the classic Speedster silhouette with its lowered, raked windshield and the double-bubble deck that pays homage to decades of open Porsches. Just 1,948 were made, a number chosen to honor the year Porsche began building cars, which gives the model an instant collectible identity that ordinary 911 cabriolets simply do not have.2019 Porsche 911 SpeedsterBring a TrailerThat combination of a revered engine, a manual gearbox, strictly limited production, and evocative styling is exactly what the market has been rewarding. As the industry has moved toward turbocharging, hybridization, and automatics, the naturally aspirated, three-pedal, limited-run Porsche has become a blue-chip target, and the Speedster is among the most desirable of them. Values have held strong, and low-mileage, well-documented cars in good colors and specs are the ones collectors chase, which is precisely the category this car occupies.My takeThis is a genuine modern collectible, and the ingredients, GT3 mechanicals, a manual, open-top drama, and a 1,948-unit cap, are exactly what this market prizes. My fair-value call is $400,000 to $460,000, and I would expect a well-preserved, well-documented, nicely specified car to land in the upper half of that, with the Heritage and carbon details helping.AdvertisementAdvertisementThe buying advice is about protecting the premium. Confirm the full service history despite the low mileage, plan for tire age, get a Porsche specialist inspection, and make sure the books, tools, and covers are all present with a clean history. Decide too whether you intend to preserve or drive it, because the money here rests on preservation. Do that, and you are buying one of the most desirable open-top Porsches of the modern era.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
