Which day of the week and month of the year do Porsche auctions close highest? Real data from 1,200+ closed BaT & PCarMarket sales — something the platforms themselves don't publish.
Average final sale price by auction close day · colored by vs-average percentage
Average final sale price by calendar month · bars colored vs overall average
Data covers closed sales from BaT and PCarMarket with confirmed close dates. Prices filtered to $10k–$500k to exclude outliers. Only auctions with a recorded sale date are included — passed/no-sale auctions are excluded.
"vs average" percentages compare each day or month to the overall dataset mean. Day of week is based on the auction close date in UTC. Use the model filter tabs to isolate 911, Cayman, or Boxster results.
Mix of car models and trim levels varies by day — higher-end cars may cluster on certain days, which can influence averages. Use as a directional guide, not a guarantee. Rare trims and GT variants can skew small sample days.
Data updates automatically with each scrape cycle. Seasonal and day-of-week patterns sharpen as more closed sales accumulate. Results shown are from 1,200+ confirmed closed auction results.
