RennPulse — Porsche Market Intelligence

Live Porsche auction tracker with fair value estimates. Track 911s, Caymans, and Boxsters across BaT, PCarMarket, and Cars & Bids.

RennPulse turns every Porsche auction into a data-driven decision. Installed on your browser, RennPulse overlays real fair-value estimates directly on Bring a Trailer, PCarMarket, and Cars & Bids listings — so you stop guessing whether a 996 Turbo at $68K is a steal or a stretch. — WHAT IT DOES — • FAIR-VALUE OVERLAY — On any eligible Porsche listing, RennPulse injects a clean overlay showing estimated fair market value, recent comps, and where the current bid sits in the price distribution. • LIVE ACTIVE AUCTIONS — Open the popup to browse every active Porsche auction across BaT, PCarMarket, and Cars & Bids in one unified view. No more juggling six tabs. • HISTORICAL SALES SEARCH — Search completed sales by model, year, mileage, and transmission. See what cars actually sold for — not what Hagerty says they're worth. • WATCHLIST + ALERTS — Star any auction to track it. Get notified when prices move or an auction is ending. — BUILT FOR — • Porsche enthusiasts who watch auctions daily • Buyers tired of "gut feel" pricing • Sellers setting reserves • Collectors tracking the 911, Cayman, Boxster, and GT markets — COVERAGE — Air-cooled 911s, 964, 993, 996, 997, 991, 992, Cayman/Boxster (986, 987, 981, 718), Panamera, Macan, Cayenne, and GT variants (GT2, GT3, GT4, GT3 RS). — PRIVACY — RennPulse only reads auction page data (model, year, mileage, current bid) to generate valuations. We don't collect personal information, track you across the web, or sell your data. See our privacy policy at rennpulse.com/privacy. — FREE BETA — RennPulse is currently free during open beta. Premium features (unlimited alerts, advanced filters, arbitrage scoring) will be available in the paid tier at launch. Questions or feedback? info@rennpulse.com
