🏷️

Price vs. Market Average

0 – 45 pts

We compare the listing price against a benchmark average for each model (911, Cayman, Boxster). A car priced at the average earns ~25 pts. Every percent below average adds points — a car priced 30%+ below market can earn the full 45. Priced above market? Scores drop toward 0.

📍

Mileage for Age

0 – 30 pts

We calculate expected mileage based on the car's age (~12,000 mi/year). A car with half the expected miles scores near the maximum. A car with double the expected miles earns close to 0. Low-mileage examples are rewarded; high-mileage examples are penalised.

📅

Model Year

0 – 15 pts

Newer cars score higher, reflecting more modern safety, tech, and powertrain refinements. A 2024 model earns close to the full 15 pts; a 2004 model earns closer to 0.

🎯

Auction Badge Bonus

+5 or +10 pts

Auction listings can earn a bonus:
No Reserve +5 pts — the seller has committed to selling at any price, creating a genuine price-discovery opportunity.
Great Deal +10 pts — flagged as an exceptional value by our scoring algorithm.

Bid Gravity — Auction bids accelerate sharply in the final hours, so a low current bid with 4 days left is not a real price signal. We automatically dampen the price component based on time remaining: 4+ days out the price score counts for only 30%, rising to 100% in the final 24 hours. The score tooltip will show "Xd left — Bid Gravity applies" when this is active. Learn more →

Benchmark averages — Price benchmarks are based on aggregated market data for each Porsche model and are periodically updated as the market shifts. They are a guide, not a guarantee.

Porsche GT3 For Sale

The Porsche GT3 is the naturally aspirated, track-bred 911 — no turbos, no compromises. From the 996 GT3's Mezger-engine purity to the 992 GT3's flat-six screaming past 9,000 rpm, every generation has been defined by exceptional high-revving character and genuine track capability.

GT3s hold value exceptionally well and frequently trade above original MSRP at auction. Manual transmission GT3s (991.1 and earlier) command a premium over PDK equivalents. FlatSixFinder tracks GT3 listings across all generations from BaT, Cars & Bids, PCarMarket, and Hemmings with deal scores sourced from real closed-auction data.
