The five marketplaces behind every number on this page. Your estimate is the anchor for a reserve; where you list decides the room bidding on it.
- The largest audience in collector cars — more Porsche bidders than anywhere else.
- Curated listings, written up by their specialists. Presentation is the house style.
- Flat listing fee and no commission on the sale — the buyer pays the platform fee.
- Free to list — the buyer pays the platform fee.
- Built for modern collector cars; water-cooled 911s are its home turf.
- A faster, less formal process — a good room for driver-quality cars.
- Porsche-only. Every bidder arrived looking for a Porsche.
- A strong room for the special cars — paint-to-sample, manuals, low miles.
- Smaller than Bring a Trailer, but the audience is exactly your buyer.
- International reach, with deep bidding from the UK and Europe.
- A managed service — they prepare and run the listing with you.
- Strong results for rare and special cars.
- The longest-running name in the hobby — a deep bench of traditional collectors.
- Three ways to sell: auction, make-offer, or a classified ad with print included.
- Flat listing fee and no commission — and an auction that misses its reserve rolls into a make-offer listing.

How the valuation works.
The headline number comes from a regression fitted to the verified sales — 494 stock cars once modified builds are set aside. It prices your car from its variant, mileage, transmission and body, with the market's drift over time and the differences between auction venues held constant, and it is always priced at the current month. The range around it is an 80% prediction interval — where most comparable cars actually land — not the widest and narrowest sales ever recorded.
Underneath, the band lookup still runs as a check: the median of your exact variant-and-mileage band from 2021 onward. When the band and the model disagree by more than 20%, the result says so and shows the comps. Hammer prices exclude the buyer's fee, so a buyer's all-in cost at auction runs higher than any figure here. Full methodology.
Worked examples.
Three specifications, valued live by the same tool above — each link opens the calculator pre-filled, so you can change one variable and watch the range move:
- 2001 Carrera Cabriolet, 6-speed, 62,000 miles — the most common 996 specification there is.
- 2002 Turbo coupe, 6-speed, 45,000 miles — where the manual premium is largest.
- 2002 Carrera coupe, 6-speed, 48,000 miles, IMS replaced — the measured IMS adjustment, applied.
Questions, answered plainly.
Are these hammer prices or asking prices?
Hammer prices — the winning bid at auction, with the buyer's fee excluded. Asking prices are tracked in a separate dataset and are never blended into these valuations, because asking prices run systematically above what cars actually sell for.
How many sales is my valuation based on?
The dataset holds 543 verified auction sales across Bring a Trailer, Cars & Bids, PCarMarket, Collecting Cars and Hemmings, from 2017 to today. The valuation model is fitted to 494 of them — every stock car, with modified builds set aside — and the count beside your result is the number of verified sales behind your variant. The band check under the estimate uses 437 sales from 2021 onward.
What does IMS work do to a 996's value?
In the valuation regression — 494 verified sales, with variant, mileage, transmission, body, venue and sale date held constant — a documented IMS bearing replacement adds about 9.6% for the M96-engine cars (Carrera, Carrera 4, 4S, Targa). The tool applies it when you tick the IMS box — and the premium attaches to the paperwork, so keep the dated invoice.
Why is a specific car priced outside the range?
The likely range is an 80% prediction interval, so about one comparable car in five still sells outside it. Condition, service history, options, colour and presentation are the usual reasons — the model can't see them, so it prices the typical car and shows its work. Variants with few sales behind them (GT3, GT2, Turbo S) are flagged low-confidence on the result.
