How US used-car listing prices vary by make, mileage, and region across the big marketplaces — measured through structured used car price scraping.

The used-car market is huge, fragmented, and priced inconsistently — the same model varies widely across marketplaces and regions. Seeing that variation means used car price scraping across CarGurus, Cars.com, and AutoTrader.

This report uses web scraping of public listings to measure how prices vary by make, mileage, and region, and how listings age. It is context for any dealer, marketplace, or analyst relying on automotive data scraping or a pricing feed.

Key findings at a glance
Three patterns stand out across the listing data. (Figures are illustrative previews — the full report breaks them down by make, mileage and region.)

Wide
price spread for the same model across sites

Mileage
the strongest price ...
... driver after model

Days
listing age signals over/under-pricing

Key finding 1: mileage drives price after model
Once model is fixed, mileage is the biggest price lever, with value dropping in clear bands. Trim, condition, and region matter, but mileage sets the baseline.
Capturing this means used car price scraping with structured fields — make, model, trim, year, mileage, region — so prices compare like for like rather than across mismatched vehicles.

Key finding 2: the same car varies by marketplace and region
The identical vehicle can list at different prices across sites and regions. The sample shows spread (illustrative).
CarGurus: $18,400 — Deal-rating pressure
Cars.com: $18,950 — Dealer-heavy
AutoTrader: $19,200 — Broad mix
Only cross-marketplace used car price scraping reveals these gaps, which is exactly where buyers and dealers find edge.

Key finding 3: listing age is a pricing signal
How long a car sits is a strong signal — fast-moving listings are keenly priced, stale ones are over-market. Used car price scraping that tracks listings over time, with a timestamp and first-seen date, surfaces days-on-market and price drops, which dealers use to reprice and buyers use to negotiate.

What the underlying data looks like
The report is built from listing records like the one below — the structure buyers receive in a sample.
{
"marketplace": "CarGurus",
"listing_id": "CG-88231",
"make": "Example",
"model": "Sedan",
"trim": "SE",
"year": 2021,

}

Aggregated to a make-and-region view, the data rolls up into a flat file analysts can model on:
make,model,mileage_band,region,avg_price,avg_days_on_market
Example,Sedan,30-60k,Midwest,18400,28
