🏷️

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 GT4 RS For Sale

The 718 Cayman GT4 RS takes the GT4's 4.0L flat-six — the same block as the 911 GT3 RS — and extracts 493 hp with a 9,000 rpm redline and intake trumpets routed through the rear windows. PDK only, sold in limited allocation, and priced accordingly on the secondary market.

Used GT4 RS listings frequently exceed original MSRP; condition, mileage, and documentation drive the spread. FlatSixFinder's deal scores use real BaT and PCarMarket closed-sale data to identify the rare examples priced at or below genuine market value.
