Used auto vehicle purchases from dealers count vehicles acquired from dealer channels rather than directly from consumers.

It is one component of a used-auto retailer's inventory sourcing mix.

CarMax example

CarMax purchased 150,619 vehicles from dealers in fiscal 2026, up 4% from the prior year.

CarMax uses its MaxOffer digital appraisal product as one dealer-sourcing channel.

Why dealer sourcing matters

Dealer purchases can expand access to inventory and help fill gaps in make, model, age, mileage, or price-point mix.

But sourcing economics can differ by channel.

CarMax states that inventory acquired from third-party auctions or dealers is generally less profitable than inventory acquired through its in-store and online consumer appraisal products.

Read the mix, not just the count

Dealer purchases should be paired with Vehicle Purchases from Consumers, retail unit sales, wholesale dispositions, and gross profit per unit.

A rising dealer mix may improve availability while changing acquisition economics.
