About PistonAlpha

PistonAlpha is an independent collector car intelligence platform. We track 47,032 active listings across 165 model series, updated daily from dealers and auction houses across Europe and the US.

We aggregate and analyze the collector car market so you don't have to check a dozen sites. Every listing is scored for investment potential using our proprietary algorithm that considers price positioning, mileage, variant desirability, market trends, and more.

Our historical price data spans decades of auction results and market listings, inflation-adjusted and broken down by generation and variant. Whether you're buying your first classic or managing a collection, we give you the data to make informed decisions.

• Automated crawling — listings from TheParkingEU, Elferspot, Nettiauto, Blocket, and more, refreshed multiple times daily
• Auction tracking — results from Collecting Cars, Bonhams, RM Sotheby's, Artcurial, and Bilweb
• Investment scoring — every listing scored 0–100 based on price, mileage, variant, trend, and market positioning
• Price history — inflation-adjusted historical prices from auction records, with regional EU/US overlays
• Market analysis — scatter plots, movers, comparisons, and model-level deep dives

PistonAlpha was built by car enthusiasts who got tired of manually tracking prices across fragmented marketplaces. What started as a personal spreadsheet evolved into a full data platform.

We are independent and not affiliated with any dealer, auction house, or marketplace. Our data and scores are unbiased — we don't take commissions or promote specific listings.
