Cross-market snapshot data captured through September 4, 2026
By CarWhere Research · Market data & verified-buyer analysis
Advertised price — the price a dealer lists before any negotiation. CarWhere verified buyer-paid price — the negotiated price a real buyer actually paid, taken from purchase paperwork submitted to and reviewed by CarWhere. This page never mixes the two.

How CarWhere calculated this
Cross-market figures combine the freshest aggregate snapshot from each tracked metro — statistics (counts, means, medians) distilled from live inventory searches run on CarWhere, refreshed continuously, with a 14-day freshness window and one snapshot per market so nothing double-counts. CarWhere stores only aggregates, never individual listings, and advertised figures are never mixed with verified buyer-paid prices. Read the full method on the CarWhere Index methodology page.
