Timing your purchase to the right month can save thousands. This chart is built from real BaT and Cars & Bids auction results — showing average sold prices by month so you can see exactly when the market softens.
January and February consistently see softer auction results. Fewer bidders are actively searching, and motivated sellers need to move cars before spring. Best window for deals.
As driving season begins, buyer competition spikes. BaT and C&B see record participation in spring months. Expect to pay a premium if you're shopping March through May.
June through August is active but not as frenzied as spring. Auction volumes remain high, and prices stabilize near the annual average. Decent time to find specific specs.
October through December brings a second window. Convertibles and weekend cars see price softening as buyers put off purchases until spring. Coupes hold value better.
BaT and C&B auctions reflect true market demand in real time. Private listings on Cars.com and Carvana often lag 4–8 weeks behind auction trends — watch both.
GT3, GT4, and Turbo S variants are supply-constrained year-round. Seasonal dips are minimal for these. Focus timing strategies on base Carrera, Cayman, and Boxster trims.
Completed auction results from BaT's Porsche listings — the largest enthusiast auction platform in the US. Each record includes the final hammer price, mileage, year, and auction close date. Only sold (not passed) auctions are included.
Completed auction results from PCarMarket — a dedicated Porsche auction platform with hundreds of 911, Cayman, and Boxster transactions going back to 2019. Each record includes final sale price, mileage, year, trim, and close date.
Results are grouped by calendar month and averaged across all transaction sources. Outliers above $500k are excluded. Data covers 1,200+ closed sales from 2019 to present and updates automatically with each scrape.
Auction prices skew toward enthusiast-grade examples in above-average condition. High-mileage or project cars are underrepresented. Use these figures as directional guidance, not absolute valuations for any specific car.
