BaT, PCarMarket, Cars & Bids, eBay, Collecting Cars, and more — each with its own search, its own alerts, and its own interface. By the time you spot an underpriced car, someone faster already bid.

Under The Hood
Generic car valuations treat every make the same. Our model uses gradient-boosted machine learning trained exclusively on Porsche transaction data — with recency-weighted comparable analysis, outlier filtering, and continuous weekly retraining to adapt as the market moves.
Features
Add any Porsche model or spec to your watchlist. We surface matching auctions across BaT, PCarMarket, and Cars & Bids automatically.
Set a price target and get notified the moment a matching car lists below your threshold — on any platform.
Our engine flags cars priced materially below their fair-value range, so you see opportunities before they sell.
Full sale history for every Porsche we track — price, mileage, spec, platform — searchable and filterable.
Aggregate market data by generation: median prices, YoY trends, volume, and days-to-sell for each model family.
