Used-car inventory aging: what to do with old stock

Updated October 9, 2026·1 min read
Short answer

Track how many days each car has been on the lot and review the oldest weekly. Holding costs, such as financing, insurance, depreciation and space, add up daily. Set review points (for example at 30, 45 and 60 days) and decide at each: reprice, improve the listing, promote or wholesale.

Why age matters

A car sitting unsold costs money every day and loses value as the market moves. Older cars also tend to be the ones with something wrong with the price, the photos or the description.

A review routine

  1. List vehicles by days on lot, oldest first.
  2. For each past your review point, check price against comparable listings.
  3. Refresh photos and description.
  4. Promote it in a campaign or on Marketplace.
  5. If it still does not move, consider wholesaling to free the cash.
