The Dataset
352 Porsche 997 auction sales, all collected and verified, hammer prices only. This page describes what the data is, where it comes from, and how it grows.
Coverage by source
| Bring a Trailer | 212 sales |
| Cars & Bids | 140 sales |
Fields on every sale
Price (hammer, USD), sale date, model year, model, mileage, body, drivetrain, transmission, exterior color, the listing URL, the source, and notes for documented items the listing states: bore scope results, IMS work, coolant pipe work, PCCB, Sport Seats, and modifications. If a listing doesn't document it, the field stays empty. Nothing is inferred.
How it grows
New sales are collected as auctions complete, and the backfill continues into earlier years. Coverage today is heaviest in 2025–2026 and thinner before that; the counts on this page are computed from the dataset itself, so what you see is what the calculator holds.
