It is offered on Bring a Trailer by a dealer with bidding at $114,000 and about a day remaining. The hook is a tastefully modified, last-of-its-kind manual Turbo, with the original components included in the sale.2007 Porsche 911 TurboBring a TrailerWhat it's worth right nowThe 997.1 Turbo manual coupe is a firmly established modern collectible, and the numbers reflect it. According to Classic.com, these cars carry a market benchmark of around $105,102 and an average sale price of $111,712, with clean examples generally trading from roughly $85,000 to $150,000, depending on mileage and specification. Recent comparable sales include $146,800 for a 2008 with 11,000 miles and $118,000 for a 2007 with 38,000 miles.AdvertisementAdvertisementA major reason for those strong figures is that this is the last manual, Mezger-engined 911 Turbo, a distinction that supports firm-to-rising values and commands a clear premium over the Tiptronic automatic, which averages closer to $75,000. Mainstream guides like Kelley Blue Book sit far lower, around $78,500, reflecting a conservative dealer benchmark rather than the enthusiast-auction reality.2007 Porsche 911 TurboBring a TrailerAt $114,000 with about a day remaining, the bidding is right at the market benchmark rather than below it, unlike some earlier-stage auctions. Fair value for a clean, well-modified, low-mileage manual like this realistically lands in the $110,000 to $120,000 range, with the undone service items below arguing against pushing far past that.Condition and detailsThe car is finished in Slate Gray Metallic over black leather and rides on 19-inch HRE P40S wheels, with a genuinely desirable and cohesive modification list: Motion Control adjustable dampers with Eibach springs and Tarett Engineering suspension components, a modified exhaust with an aftermarket X-pipe and catalytic converters, Ultimate Motorwerks engine management, and 997.2-specification intercoolers. Crucially, the original suspension parts and factory exhaust are included, along with an unused Speed Tech catted X-pipe, making the modifications effectively reversible. Full paint-protection film is applied, and the seller notes the rear bumper appears to have been touched up near the driver-side taillight, though the owner and Carfax report no accident.2007 Porsche 911 TurboBring a TrailerBecause these are high-quality, reversible upgrades with the stock parts retained, the market generally values a car like this at roughly the stock benchmark rather than at a premium, since buyers rarely pay to recover modification costs. That is not a criticism, simply the right way to frame it: you are buying a well-sorted, upgraded Turbo at close to clean-stock money, with the ability to return it to standard.2007 Porsche 911 TurboBring a TrailerThe key due diligence point concerns two well-known Mezger maintenance items, and the seller has been transparent that neither has been done. The coolant pipes use press-fit fittings held by adhesive that can loosen over time and dump coolant, so owners weld or pin them, typically a few thousand dollars in-car. Separately, the intake camshaft sleeve can spin and throw a P0021 code, addressed by pinning the camshaft, a job usually done with the engine out. A commenter's $15,000 to $20,000 estimate reflects a worst-case scenario of doing everything with the engine removed; the two core jobs alone are closer to a few thousand each, but they should be budgeted and negotiated accordingly.The offerSpecificationDetailMakePorscheModel911 Turbo Coupe (997.1)Year2007Mileage26,000 milesEngineTwin-turbocharged 3.6-liter Mezger flat-sixPower480 hp and 460 lb.ft of torque (factory rating, now modified)Transmission6-speed manualDrive typeAll-wheel driveExterior colorSlate Gray MetallicInterior colorBlack leatherCurrent bid$114,000, with about a day leftInterested in this 2007 Porsche 911 Turbo? View the listing here.What makes the 911 Turbo uniqueThe 997.1 Turbo holds a special place in the 911 lineage as the last Turbo to use the legendary Mezger engine, a motorsport-derived flat-six with roots in Porsche's GT1 and racing programs. Unlike the later direct-injection units, the 3.6-liter Mezger is prized for its robustness and tuning headroom, and in this car's twin-turbocharged form, it delivered supercar performance with everyday usability, all-wheel-drive traction, and the security of a proven design.2007 Porsche 911 TurboBring a TrailerAdvertisementAdvertisementThe six-speed manual is central to the appeal. As Porsche moved subsequent Turbos to the PDK dual-clutch automatic, the 997.1 became the final Turbo offered with three pedals, and that combination of a rev-happy Mezger engine, a manual gearbox, and understated coupe styling has made it one of the most sought-after modern 911s for driving enthusiasts. Values have responded accordingly, with clean manual cars appreciating as collectors recognize the significance.My takeThis is a compelling example of an important modern 911, and the recipe here is a strong one: the last manual Mezger Turbo, low mileage, a handsome color, a genuinely tasteful and reversible modification list, and the original parts in the sale. For a buyer who wants a well-sorted, upgraded Turbo without hunting for a stock car and modifying it themselves, this checks a lot of boxes.I would place fair value in the $110,000 to $120,000 range, so the current $114,000 bid is right at market rather than a bargain, as some earlier-stage auctions represent. The deciding factor is the two undone Mezger service items: I would treat the coolant-pipe fix and camshaft pinning as budgetable costs and let them cap the bid rather than chase the car far past $120,000 to $125,000. Get a pre-purchase inspection focused on those items and the modification quality, factor in the service outlay, and this is a genuinely desirable manual Turbo at a reasonable price.Disclaimer: This post is for informational purposes only.
