FLAT SIX VALUE
The parent site

Independent Porsche valuation, generation by generation

Flat Six Value is the parent home of a family of valuation sites — one for each flat-six Porsche 911 generation. Every site runs the same method: verified auction sales only, median hammer prices by mileage band, and adjustments only where the data measures them. No asking prices dressed up as values, and no guessed numbers where the data is thin.

996 (1999–2005) is live today. 997 (2005–2012) is in build — its verified-sales dataset is being harvested now. 991, 993, and 964 follow as their datasets are built.

Generations

Pick your generation

Each generation gets its own site, its own verified dataset, and the same calculator and monthly market report. The method never changes — only the cars do.

Shared methodology

One method, every generation

Every Flat Six Value site is built on the same rules that made 996Value.com credible. If a number appears on any site in this network, it was computed from verified sales — and where the data is too thin, the site says so instead of estimating.

  • Verified auction hammer prices only. Buyer fees are excluded. Asking prices are tracked separately and never blended into sold-price medians.
  • Five sources, checked sale by sale: Bring a Trailer, Cars & Bids, PCarMarket, Collecting Cars, and Hemmings.
  • Band medians, not averages. Values come from the median of comparable sales in the car's mileage band, with the observed range shown.
  • Measured adjustments only. A premium (an IMS replacement, a manual gearbox) is applied only when the dataset measures it — otherwise it is shown as not yet measurable.
  • Thin data is disclosed. Below three comparable sales, the sites list the actual sales instead of printing a valuation.

Findings from the 996 dataset

The kind of analysis each generation site publishes — measured from its own verified sales, on 996Value.com.

+14%

The 3.6-litre premium is real: 996 Carrera 3.6 cars outsell the 3.4 at the median, manuals only, on the banded basis.

+7.8%

A documented IMS bearing replacement measures a real premium in the 996 data — the first adjustment the network ever published, because it was the first one the data proved.

$9–13k

The 996 Turbo coupe premium over the cabriolet at matched miles under 50,000 — real, but a fraction of the $25–40k figure repeated in forums.
