SpecScan — VIN Scanner & Vehicle Valuation

Detect VINs on any car listing, capture the page's options and window sticker, and get an instant SpecScan market valuation.

SpecScan turns any car listing into an instant, comps-backed market valuation. • Click the SpecScan icon on a dealer listing — the extension finds the VIN, mileage, and asking price automatically. • It reads what the page already shows: the factory options list and the window sticker, so the valuation reflects how the car is actually equipped. • Get the market value, realistic price range, confidence level, deal rating vs. the asking price, and a dealer trade-in estimate. • Optional auto-detect mode shows a badge the moment any listing loads. • Right-click any VIN in text to value it instantly. Requires a free SpecScan account — generate your API key at specscan.net (Profile → API Access). Free plan includes 5 scans/month; paid plans up to 10,000.
