996Value.com is an independent project run by Wesley Neese, a Porsche 996 owner, built to answer one question: what is a 996 actually worth? The site combines a free valuation calculator with market research, all grounded in verified auction hammer prices rather than asking prices or asking-price indexes. It is not affiliated with or endorsed by Porsche AG or Bring a Trailer. Follow along on TikTok: @996cabo.

Methodology

Data source: verified auction sales only (2017–2026), covering 1999–2005 Porsche 911 (996) cars across 13 variants — Bring a Trailer, Cars & Bids, PCarMarket, Collecting Cars and Hemmings. The dataset grows every month; the live count is in the header of every page.
Hammer-price basis: all prices are hammer prices; buyer fees are excluded so figures reflect what the car sold for, not the all-in transaction.
Time, priced in: the model carries a sale-month term — measured at about +3.3% a year across 2017–2026 — and always prices at the current month, so a 2021 sale informs the estimate through the trend instead of counting the same as a sale last week.
Model first, bands as the check: the headline estimate comes from a regression on variant, mileage, transmission, body, venue and time, fitted to every stock car in the dataset (modified builds set aside). The older band-median lookup still runs underneath, and when the two disagree by more than 20% the result flags it and shows the comps.
What auction data misses: BaT skews toward enthusiast-owned, well-presented cars. Private-party and dealer sales aren't in this dataset. Treat these numbers as the auction market, not the whole market.
Thin-data policy: variants with fewer than 20 verified sales (GT3, GT2, Turbo S) are flagged low-confidence on every result, and the likely range is a statistical prediction interval — it widens honestly where the data is thin instead of disappearing.
No invented data: every figure on this site traces to a recorded sale. Sample sizes are shown wherever a number is presented.

Data & valuation disclaimers

Valuations are directional estimates based on observed auction results. They are not appraisals, not offers to buy or sell, and not a guarantee of any selling price. Auction results reflect specific cars on specific days; condition, service history, and provenance move individual cars outside any band. Past sales do not predict future prices.
