When Ahlam suggests a price, it uses the median of comparable listings, not the average. That one choice is the difference between a price buyers accept and a price that looks reasonable on a spreadsheet but never actually sells. Here is the reasoning.
Average and median are not the same number
The average adds up every comp and divides by the count. The median is the middle number when you line the comps up from lowest to highest. When the data is clean and tightly clustered, the two land close together. Used-parts data is rarely clean.
One weird listing breaks the average
Marketplaces are full of outliers: a part listed at triple the going rate by a seller who will never move it, or a fire-sale price from someone clearing out a garage. The average chases those extremes. The median quietly ignores them.
- Five comps at $90, $95, $100, $105, and $400.
- Average: $158, dragged up by one fantasy price.
- Median: $100, the real middle of the market.
Why this matters more for used parts
Price that part at $158 and it sits. Price it at $100 and it moves. The median protected you from a single bad data point.
New parts have a list price. Used parts have a market that shifts with condition, mileage, region, and luck. That market is noisy by nature, which is exactly the situation where the median beats the average. The messier the data, the more the median earns its keep.
What you see in Ahlam
Ahlam pulls live comps for the same part and fitment, takes the median, and shows you the range it came from, so the number is never a black box. You see the middle of the market and the spread around it, then nudge up for a Grade A or down for a Grade C.
- The suggested price is the median of real, current comps.
- You see the full range, so you can position above or below the middle.
- Outliers are filtered, so one fantasy listing never sets your price.

Rarely, because you still adjust for condition. The median is the starting point for a Grade B part. A bench-tested Grade A moves up toward the top of the range, and the listing explains why.
