Cox: New-vehicle supply held steady in June, with wide brand gaps

What Cox measured in June

Cox Automotive's July 16 report, based on vAuto Live Market View data, estimates that 2.82 million new vehicles were available at the end of June. Inventory declined 2.4% from May and was mostly unchanged from June 2025.

Estimated days of supply rose to 80.3 from a revised 78 in May. Cox says the increase came mainly from a 5% month-over-month slowdown in the daily sales pace rather than from inventory growth. The daily pace was still 4.1% above a year earlier. These are attributed industry estimates, not government counts or forecasts.

The national average hides brand-level differences

Cox found that Toyota entered July with the tightest days of supply, followed by Lexus and Honda, while several Stellantis brands carried substantially more inventory. That means the negotiating environment can differ by make, model, trim, and location even when nationwide supply looks balanced.

Inventory also varied by price. Cox counted more than 688,000 vehicles listed from $30,000 to $40,000, about 24% of available units, and said 34% of inventory was listed below $40,000. Those shares describe the vehicles in Cox's dataset, not every configuration available in a local market.

Listing prices are not transaction prices

Cox estimates the average new-vehicle listing price was $49,336 in June, up 0.3% from a revised May figure and 1.4% from a year earlier. A listing price is an asking price and does not include every tax, fee, incentive, trade-in, or negotiated adjustment.

The Bureau of Labor Statistics reported separately that its new-vehicle consumer price index was unchanged from May after seasonal adjustment and 0.5% higher than a year earlier. The BLS index measures price change, while Cox's report measures dealer listings and supply; neither is a quote for one vehicle.

How shoppers can use the inventory signal

• Compare several listings for the same model, trim, options, and model year in your region.
• Ask for a written out-the-door price and verify which incentives you actually qualify for.
• Treat a high days-of-supply figure as context for comparison, not a guarantee of a discount.
• If financing, compare APR, term, total interest, amount financed, and total of payments across written offers.
