Auto cost-per-unit trend

Each point is the monthly median cost-per-unit across priced auto lots — the middle value, not an average, so one outlier truckload can’t drag the line. A live lot counts in the month it first appeared in the feed; an ended lot counts in the month it closed. Lots match the category by their title — the same category match the live feed uses — and cost per unit is the lot’s price divided by its listed unit count, where the source publishes one.

Months with fewer than 30 priced lots render as insufficient data and stay off the chart — a median over a handful of lots isn’t trustworthy. That floor gates the chart, the “Months with data” stat, and the month table above alike.

The lots behind the series come from the nine marketplaces BStalker scans: Liquidation.com, B-Stock, DirectLiquidation, 888 Lots, Via Trading, BlueLots, GovDeals, Musick, and QuickBidz. Sitewide medians, discount-vs-retail, and closing-time patterns are on the statistics page.

Auto lots cover parts and accessories — tires, batteries, dash cams, car-care products, and roof racks — plus, on GovDeals, retired fleet vehicles themselves. Fitment is the category-specific detail: a parts pallet is only worth what fits vehicles buyers actually own. Returns and overstock feed most of the accessory volume.

Auto-parts per-unit is meaningless without fitment — the same per-unit cost is a great lot or dead stock depending on what the parts fit. BStalker shows the per-unit number; fitment analysis is yours to do.

What goes into a per-unit number — bids, buyer premiums, freight — is covered in liquidation pallet costs explained, and the live lots themselves are on the auto lots page.
