Who buys in US auto sales, and is there a single national database?
- Who pays for attention here
- Franchised and independent dealers buy showroom leads via Cars.com, Cox's AutoTrader and CarGurus, alongside auto insurers and subprime lenders (head term $3.70 CPC, competition 96, measured 2026-09-01).
- What a cross-state index adds
- Cars.com, CarGurus and AutoTrader already aggregate dealer inventory nationwide; the uncovered side is license status, complaint and enforcement history from the 50 state dealer boards joined to inventory and pricing.
- Single national database?
- No federal one; the primary database is state-level. Dealers are licensed state-by-state — for example, Texas TxDMV issues GDN licenses with a public Dealer License Lookup. NHTSA oversees vehicle safety, not dealer licensing.
