More questions
Can I cite these figures in an appraisal?
Yes, as dated market statistics. Each answer echoes the exact filters it applied, and each row states its month, area and priced sample. Present them as listing evidence: the asking price when comparable cars left dealer websites.
Does it show individual cars or VINs?
No. It returns statistics (units, median and mean asking price, odometer, days on market) grouped by model, year, trim, seller or group, never a VIN. Pair a band with named comparables from the recently sold search when the report needs individual vehicles.
How many sales back each figure?
Every row states its units sold and its priced sample, the sales with an asking price behind every price figure. A row on fewer than 30 priced sales is marked as a thin sample: read it as a direction only. Widen to a model-year range or a neighboring state, or pool several states into one row, until the sample clears 30.
What does a call cost?
$3.00 per call unit, paid from your prepaid balance and only after a successful call; a refused or failed call costs nothing. Every prompt on this page is 1 unit ($3.00), so all 13 prompts come to 13 units ($39.00).
How current is the data?
It is monthly, and each month lands one to two months after it ends, so date-stamp every figure with its data month. The examples on this page are from Aug 2026. It covers US dealers only, back to January 2021, at most 12 months per call.
