This 2008 Cabriolet pairs both with just 29,000 miles in an elegant Meteor Grey over Sand Beige combination. It is on Bring a Trailer at $67,000 with three days to go.2008 Porsche 911 Turbo CabrioletBring a TrailerWhat it's worth right nowThe manual 997.1 Turbo has become a blue-chip modern Porsche. According to Classic.com, manual 997.1 Turbo Cabriolets average around $94,907 with a benchmark near $98,188, spanning from a low of $41,000 to a high of $179,500.AdvertisementAdvertisementThis car has the right ingredients: the coveted six-speed manual, the Mezger engine, Sport Chrono, low-ish mileage, and a desirable color combination. The modifications and the fraying top detailed below place it a touch below a pristine stock example rather than at the top of the range.2008 Porsche 911 Turbo CabrioletBring a TrailerWeighing the desirable specification against those points, fair value realistically lands in the $75,000 to $100,000 range, most likely the mid-to-high $80,000s to low $90,000s. At $67,000 with three days remaining, the bidding should climb into that band.Condition and detailsThe car is nicely specified and reported to be clean. Finished in Meteor Grey Metallic over Sand Beige with matching instrument dials and a Stone Grey top, it carries the Sport Chrono Package and rides on 19-inch Turbo wheels, and the twin-turbocharged 3.6-liter Mezger flat-six makes 480 horsepower, with overboost lifting torque to 505 lb-ft. Paint-meter readings indicate all original paint, and the Carfax is clean.2008 Porsche 911 Turbo CabrioletBring a TrailerThe considerations are mostly about deviations from stock. The car has an aftermarket exhaust, which the seller says retains its catalytic converters though without clear identification, and it has been lowered, so confirm what suspension was used, that the alignment and ride height are correct, and ideally that the factory parts are available, since these mods narrow the buyer pool slightly. The seller also discloses fraying in the middle of the soft top, so budget for eventual top repair and confirm the top and its hydraulics operate correctly.2008 Porsche 911 Turbo CabrioletBring a TrailerOne more note: it wears General tires, a budget brand on a 480-horsepower car, so factor in fresh premium rubber. The key reassurance is the engine: the Mezger flat-six avoids the intermediate-shaft and bore-score worries of Porsche's contemporary engines, which is a major reliability and value plus. Given the dealer's wire-only terms with no inspection contingency, arrange a pre-purchase inspection before bidding.2008 Porsche 911 Turbo CabrioletBring a TrailerAdvertisementAdvertisementThe offerSpecificationDetailMakePorscheModel911 Turbo Cabriolet (997.1)Year2008Mileage29,000 milesEngineTwin-turbocharged 3.6-liter flat-sixPower480 hp and 460 lb.ft of torqueTransmission6-speed manualDrive typeAll-wheel driveExterior colorMeteor Grey MetallicInterior colorSand Beige leatherCurrent bid$67,000, with three days leftInterested in this 2008 Porsche 911 Turbo Cabriolet? View the listing here.What makes the 997.1 Turbo uniqueThe 997.1 Turbo holds a special place in Porsche history as the last 911 Turbo to use the motorsport-derived Mezger engine, a dry-sump flat-six developed from the units that powered Porsche's Le Mans and GT1 racers. That engine is the stuff of legend among enthusiasts, both for its ferocious twin-turbocharged performance and for its bulletproof reliability, sidestepping the concerns that affect the contemporary water-cooled Carrera engines. Pair it with the increasingly rare six-speed manual and the all-weather security of all-wheel drive, and you have a supercar that is both explosively fast and genuinely usable every day.2008 Porsche 911 Turbo CabrioletBring a TrailerThat combination of a revered engine, a manual gearbox, all-wheel-drive capability, and open-top motoring is exactly why manual Mezger Turbos have become so coveted and why values continue to climb. It is a modern classic that delivers thrills and dependability in equal measure.My takeThis is a highly desirable car. The manual Mezger 997.1 Turbo is on many enthusiasts' short lists precisely because it marries supercar performance with real reliability and a proper three-pedal experience, and in Cabriolet form with a tasteful Meteor Grey over Sand Beige spec, it adds open-top drama. With 29,000 miles, it is a genuinely usable example of a modern great.AdvertisementAdvertisementFair value sits in the $75,000 to $100,000 range, with the modifications and top keeping it just below a pristine stock car, so the current bid has room to climb. The homework is straightforward: confirm exactly what exhaust and suspension were fitted and that the factory parts are available, budget for the fraying top and fresh premium tires, and get a pre-purchase inspection given the wire-only terms. Handle that, and you own one of the most coveted modern 911s, with the sky overhead.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
