The anchor is comp_014: a Black 2010 997.2 GT3, factory PCCB and FAXL, 10,000 miles, sold BaT Honolulu November 2024 at $180,000. Same color, same option set, 7,000 fewer miles than the subject. The cohort appreciated +13.5% year-over-year through 2025 (src_0060); time-adjust comp_014 to May 2026 and the anchor expands to approximately $195,000 to $205,000 before subject-specific deductions.

ANCHOR$180,000

COMP_014 · Bring a Trailer · 2024-11 · 10,000 MI · BLACK · HONOLULU, HAWAII

10k miles, PCCB yellow calipers, FAXL, Sport Chrono Plus Plus, Sound Package Plus, PASM. CA/OR/WA history, CPO 2016. Anchor comp — closest spec match to subject.

Why it is here. The closest spec match in the file: same Black-on-Black, factory PCCB and FAXL, 7,000 fewer miles than the subject. Every adjustment in this dossier runs from here. Time-adjusted to May 2026 at the cohort's +13.5% YoY appreciation rate, the anchor expands to roughly $195,000 to $205,000 before subject-specific deductions.

CEILING OUTLIER$217,500

COMP_022 · Bring a Trailer · 2024-05 · 7,000 MI · BASALT BLACK METALLIC · NEW YORK (DEALER), CA/AZ/MT HISTORY

7k miles. Basalt Black Metallic, PCCB yellow calipers, FAXL, Sport Chrono Plus Plus, Sound Package Plus, PASM. Full Kardex. Ceiling outlier — cleaner documentation than subject.

Why it is here. Lower mileage, near-identical option set, same model year cohort. This is the upper bound the auction channel will pay for a Black-spec PCCB FAXL 997.2 GT3. The subject carries 9,762 additional miles and three unresolved documentation items; the spec-clean ceiling is the anchor for the resolved-state band.

CEILING TEST · THE SUBJECTBID $225,000 · LIVE

COMP_017 · Bring a Trailer · 2026-05 · 17,000 MI · BLACK · NEW JERSEY (CONSIGNOR)

SUBJECT — live BaT auction (closes 05/29), bid activity to $225,000 (9 bids as of 05/28). PCCB confirmed. Replacement front spoiler with PPF. 17k mi.

Why it is here. The hardest ceiling test the file has: this exact chassis in this exact spec, running through live public price discovery. The auction is at $225,000 with 9 bids as of 05/28, closing 05/29. Reserve status is undisclosed (src_0017). Active bid level sits above the algebraic ceiling for an unresolved-state car. Where the hammer lands relative to that ceiling becomes a key data point for the next 997.2 GT3 dossier in this comp ledger.

RELEVANT$516,997

COMP_010 · Bring a Trailer · 2026-03 · 10,000 MI · UNKNOWN · MASSACHUSETTS / CANADA / US

10k miles, exported to Canada 2012, returned US 2023. Previously sold BaT March 2023. RS cohort reference.

Why it is here. An RS variant, not a direct comp. Included as the cohort-adjacent ceiling: the RS commands more than 2x the non-RS at comparable mileage, and the appreciation curve is pulling the non-RS toward it. The architecture-parity discovery cycle has lifted RS values first; the non-RS 997.2 GT3 cohort historically lags by roughly twelve to eighteen months.

RNM = reserve not met (no-sale high bid). Undated dealer rows are active or removed asks as of the valuation date; asks are signals, not sale prices. Ceiling-test interpretation: comp_022 ($217,500, BaT May 2024) represents a ceiling outlier — color-correct black/black low-mileage example with full Kardex. Subject lacks Kardex; ceiling is not directly reproducible. Ceiling serves as market appetite ceiling, not fair-value ceiling.

2011 Porsche 911 GT3 · 997.2 GT3 Coupé · VIN …3303. Base MSRP $115,700. It carries the two factory options the GT3 market pays for, in standard black, with one accessory missing.

Among documented 997.2 GT3 builds this one sits in the upper third. It clears the cohort median on the two options that actually move money, ceramic brakes and the front lift. It is held out of the top tier by a standard color (no paint-to-sample premium) and a missing factory accessory. A buyer's-options car, not a collector's-spec unicorn.

The forward band sits on nine eligible comps across 2.3 years: enough for a +3.3% CAGR fit, not enough to project with conviction. The 3-year p25 to p75 of roughly $192K to $256K is wider than the appraisal's resolved-state ceiling of $210K because two recent dealer-sold comps pull the p75 up. Read the band against the verdict, not in place of it. The appreciation runway for the cohort is real; the auction channel has not yet followed the dealer channel up.

The 997.2 GT3 is the closing chapter of a particular Porsche architecture: naturally aspirated Mezger flat-six, hydraulic steering, an 8,400-rpm redline, and a narrow-body coupé built around an engine that did not need a wider chassis to justify its presence. Approximately 2,256 cars were produced worldwide between 2009 and 2011, with roughly 160 US-specification examples in MY2011. Every GT3 produced after this generation moved to direct injection, the 9A1 platform, and electric-assist steering. The 997.2 GT3 sits in the same lineage position the 993 Turbo occupies on the turbocharged side: last of its architecture, carrying the premium that comes with finality.

This particular chassis, VIN WP0AC2A92BS783303, decodes via NHTSA to Porsche AG Stuttgart-Zuffenhausen, 997 GT3, MY2011, 3.8L flat-six, US-spec LHD (src_0002). Production completed September 10, 2010 per the Porsche Production Specifications sheet; retail delivery at Tom Wood Porsche Indianapolis followed November 9, 2010 at 31 miles (CarFax src_0001). The M97.77 Mezger is architecturally distinct from the M96/M97 Carrera engine; the IMS-bearing failures and intermediate-shaft bore-scoring that dog the base architecture do not apply to this drivetrain (src_0092, src_0093). CarFax records a clean title across all five owners: no accidents, no structural damage, no airbag deployments, no title brands.

The first 12,692 miles of this car's life are the spine of the file. Delivered new through Tom Wood Porsche Indianapolis on November 9, 2010 at 31 miles, with production completed September 10, 2010 per the Porsche Production Specifications sheet (CarFax src_0001, BaT listing src_0014). The VIN decodes to 9972 chassis, M97.77 engine type, Stuttgart-Zuffenhausen assembly, US-spec LHD (NHTSA src_0002). Two consecutive Indiana owners servicing exclusively at Tom Wood through May 2017: pre-delivery inspection at 13 miles, multiple annual visits, a March 2015 brake-fluid flush, the February 2017 wing/spoiler line in the record. That is the highest-quality service-chain anchor available on a private-sale modern Porsche, and it is the reason this file does not break before $190,000.

After Owner 2 the chain disperses. Owner 3 titled the car in Florida and stored it in New York for seven months, then passed it to Owner 4 in Manhattan through a Porsche Gold Coast pre-purchase inspection in February 2018. Owner 4 averaged 518 miles per year over three years; the Manhattan Motor Cars module-replacement event occurred 289 miles into that tenure. Owner 5 in Short Hills, New Jersey held from January 2021 through May 2026 consignment at 453 miles per year. Both Owners 4 and 5 sat the car under the static-storage envelope: tires age in place, brake fluid degrades hygroscopically, and the most recent service records cover only fluids and consumables.

Color state is factory-original. CarFax records "Vehicle color noted as Black" at every title and service event across all five owners (src_0001). Paint-protection film covers the full front end; seller-disclosed paint-meter readings of 11.6 to 12.7 mils across the PPF panels are consistent with standard 8-mil PPF over approximately 3.6 to 4.7 mils of factory base/clear (src_0006). That arithmetic rules out a thick repaint over filler beneath the PPF. It does not substitute for a paint-meter pass after PPF lift on the front bumper at PPI. Matching-numbers state is not claimed in the listing; PPS cross-check against case stampings at PPI is the path to confirmation. The IMS-bearing failure and bore-scoring failure that dog the M96/M97 Carrera architecture do not apply to the Mezger M97.77 dry-sump engine in this car (src_0092, src_0093). It is a different engine in a different ecosystem.

The chassis has no prior public listing history before the Powertech consignment (src_0091). Adjacent-VIN clusters (WP0AC2A95BS783442 at comp_001, WP0AC2A98BS783354 at comp_016) confirm the subject's position inside the documented MY2011 US-allocation production sequence.

The June 2018 Manhattan Motor Cars line is the file's central history-related risk. CarFax records "engine/powertrain computer/module replaced" at 13,164 miles, 289 miles into Owner 4's tenure (src_0001). The replacement was unprompted by any prior fault code or service interval that surfaces in the record. If the DME was replaced with a factory-calibrated VIN-matched unit, the value impact is zero. If it was replaced with a non-matching unit or a tuned map, the deduct is $3,000 to $8,000 and the buyer's recourse is legal rather than mechanical. The variocam camshaft-actuator bolt defect is the second buried risk: factory M6 bolts in MY2010-2011 cars back out under sustained high-rpm use, with documented engine seizures in extreme cases (Rennlist src_0128, src_0129). The TPC Racing M7 upgrade is the documented preventive fix. The service record contains no entry confirming it has been performed. PIWIS Cam Deviation monitoring at PPI either closes the question or schedules an $800 to $2,500 preventive bill.

Mid-volume BaT consignment specialist with 34 lifetime listings and 636 likes. No major complaints identified in public forums. Reputation is neutral-to-positive for enthusiast-grade inventory.

Powertech Select Motorcars (BaT handle powertechselect) is a consignment dealer in Lake Hopatcong, New Jersey. The associated service shop Powertech, founded 1991, is positively cited in Rennlist's Northeast US specialist threads, with two independent endorsements in a 2023 thread and no negative mentions across the searches conducted (src_0084). Principal Shawn Cudnik holds a PCA National Instructor credential, the kind of certification that carries more weight when you are asking whether a car was tracked than when you are reading it off a website. NJ dealer license status could not be confirmed in a public lookup; continuous BaT and CarGurus consignment activity since June 2016 implies active licensure.

On BaT, Powertech Select carries 636 lifetime likes and 34 lifetime listings since 2016: a mid-tier platform presence, competent for this price tier, not the top-tier specialist-buyer-pool activator that Ryan Friedman Motor Cars is on the dealer side. The listing is disclosure-forward in a way that should be acknowledged: PPF, replacement front spoiler, tire date codes, bumper indentations, spoiler chip, and coolant-line status all surfaced unprompted in the listing copy or in the comment thread when asked. The narrative discipline is medium-and-honest. No scarcity framing. No one-of-N claims. No color-rarity amplification. The listing emphasizes engineering specification (titanium rods, dry-sump, dynamic engine mounts) without constructing a premium narrative around it.

What did not surface proactively was the June 2018 Manhattan Motor Cars module replacement. On a $200,000-plus car with a CarFax line that reads "engine/powertrain computer/module replaced," proactive disclosure is what a disclosure-forward consignor does. The omission says either the seller does not have the work order in the file or did not prioritize surfacing it. Both readings support requesting it directly, and treating silence after the request as adverse.

The auction's thin activity is its own signal. 9 bids at $225,000 with a day left is well below what this cohort usually attracts on BaT, and the current bid already sits above the dossier's algebraic ceiling for an unresolved-state car. Either the reserve is set above where bidders are willing to go, the disclosed module-replacement line is suppressing engagement, or both. A bidder serious about this car should anchor on the conditional $195,000 / resolved $210,000 framework, ask the three documentation questions in the comment thread before close, and let the answers (or the silence) move the bid.

Mandatory floor items are pre-checked; toggle conditional and contingent lines as the dossier's findings apply to your bid. The checklist below names what to resolve before the hammer.

The auction closes 2026-05-29. The six action items below are sequential, not optional.

1. Call Tom Wood Porsche (317-848-5550) before the close. Request the full service record for VIN WP0AC2A92BS783303, specifically the February 7, 2017 work order (which adjudicates the wing/spoiler question against the BaT-disclosed replacement front spoiler) and any variocam-bolt or coolant-line preventive entries.
2. Request the Manhattan Motor Cars work order for June 26, 2018 from the seller (post it in the BaT comment thread) or directly at 212-594-6200: DME scope, part number, VIN-coding confirmation for the module replacement. Treat silence after a directed request as a material adverse signal and harden the deduct.
3. Query recall.porsche.com with VIN WP0AC2A92BS783303 before signing. NHTSA campaign 11V285000 (center-locking hubs) covers production through September 17, 2010; remedy is free at any authorized Porsche dealer, but this is a blocks-close item until confirmed closed.
4. Commission a Mezger-capable PPI with PIWIS access if the auction goes to your bid-to. PCCB rotor thickness at all four corners is the highest-consequence single line ($3,000 to $25,000 exposure depending on axle state); PIWIS DME VIN-match and over-rev log; PIWIS Cam Deviation monitoring for the variocam bolt question; paint-meter beneath PPF lift on the front bumper.
5. Plan to replace the tires before first drive. Seller-confirmed date codes 4120 and 4420 place the Michelin Pilot Sport Cup 2 set at the October-and-November 2020 manufacture date. That is 5.5 years old, past the manufacturer's 5-year service recommendation regardless of tread depth; budget $2,500 to $4,000 for correct-fitment replacement.
6. Flush the brake fluid as the mandatory first service. Last documented flush was March 5, 2015 at Tom Wood Porsche. Eleven years. Hygroscopically degraded regardless of mileage. Non-negotiable before any driving.

Post-purchase realistic cost band: $8,000 to $14,500 for tires, brake fluid, battery, and post-delivery service. One-axle PCCB replacement adds $14,000 to $18,000. Both-axle PCCB adds $25,000. Bind agreed-value coverage at the purchase price before transport.

Bid up to $195,000 with the documentation conditional. Pay no more than $210,000 with the three items resolved. Walk above $242,000 in any state.

Immediate post-purchase realistic case: $8,500 – $14,500.

Worst case: $18,000 – $38,000.

1. PCCB rotor measurement at all four corners. The single largest post-purchase variable: $0 in spec, up to $25,000 if both axles are depleted. Cannot be assessed from photos.
2. PIWIS DME scan for VIN-coding, over-rev log, and factory calibration. The 2018 Manhattan Motor Cars 'engine/powertrain computer/module replaced' line (src_0001) is the file's central documentation gap. PIWIS confirms whether the unit is factory-calibrated and VIN-matched.
3. PIWIS Cam Deviation check for the variocam bolt fix. MY2010-2011 peak-risk window for factory M6 bolts backing out under sustained high-rpm use (Rennlist src_0128, src_0129). The TPC M7 upgrade is not documented in the service record.
4. NHTSA recall 11V285000 closure via recall.porsche.com. Center-locking hubs; the subject's production date falls within the campaign window. CarFax self-report is not closure confirmation. Blocks close until cleared (free remedy at any authorized Porsche dealer).
5. Paint-meter beneath partial PPF lift on the front bumper. Seller-disclosed readings of 11.6 to 12.7 mils are consistent with 8-mil PPF over factory paint. Verify under a partial PPF lift to rule out filler or repaint.
6. Coolant-line coupling visual inspection. Seller confirms the lines are not pinned. This is the 997.2 GT3 platform's highest-consequence failure mode — mandatory pre-track service, and prudent for street-only buyers to check for weeping or cracking.
7. Work-order requests: Tom Wood (02/07/2017) and Manhattan Motor Cars (06/26/2018). Two documented but unscoped service events: the wing/spoiler entry and the engine/powertrain module replacement. Silence after a directed request hardens the related deduct.

Request full Tom Wood Porsche work order and Manhattan Motor Cars invoice before bidding; these two documents either unlock the $205K ceiling or justify a $170K-$185K revised bid.

Each question is paired with a three-state interpretation key. A green answer holds the dossier's resolved-band number. A yellow answer drops you back to the unresolved band. A red answer pushes you off the car or into walk-at territory.

Molly cited 129 sources in this dossier, weighted by tier as 9 Tier 1, 49 Tier 2, 71 Tier 3. Every claim above traces back to one or more of them via inline citation tokens. The full archive, including titles, URLs, types, and accessed dates, is searchable below.

Sources. Two hundred researched, 127 cited after deduplication: Tier 1 nine sources, Tier 2 forty-nine, Tier 3 sixty-eight. Twenty-two direct auction comps over thirty months, twelve dealer-sold comps, four unsold signals.

Conflicts the file resolved. The wing/spoiler-event identity question: CarFax records "wing/spoiler installed" at Tom Wood Porsche February 7, 2017, while the BaT listing separately discloses a replacement front spoiler. The Porsche expert adjudicated these as two distinct events. The 2017 entry most plausibly refers to rear-wing service; the front spoiler is an undated cosmetic pre-sale item with no CarFax record. The buyer should confirm at PPI. The production count question: three sources cite different US-allocation figures, adjudicated to 2,256 worldwide and 715 North America for MY2010-2011 combined as working figures. The approximately 160 MY2011 US-only number is single-sourced and treated as approximate.

What this file did not close. The Manhattan Motor Cars module scope is undetermined: CarFax records the event, the replaced component is unknown. The 2025 front-suspension replacement exists only through seller representation; invoice corroboration is required to determine OEM vs. aftermarket. The Porsche Production Specifications sheet scope on engine and gearbox numbers is unconfirmed; cross-check at PPI. Individual BaT gallery photos were not vision-reviewed due to JPEG token constraints; PPI shop will review the gallery in context. The reserve level on the live BaT auction is undisclosed; the $225,000 figure is the current bid, not the reserve. No named marque historian commentary was found specifically on the 997.2 GT3, a structural gap in the public record, not in this file's research.

This is the first Molly dossier on any 997.2 GT3 chassis. Where the hammer lands on this live auction becomes the calibration baseline for future files in this cohort.
