About RennPulse — Porsche Market Intelligence
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
