Showroom traffic was strong in the first few months of the calendar year as new-car shoppers were looking to score a deal before possible price increases due to U.S. import tariffs. GMC dealer inventory consequently diminished during that period, but now, it has risen mildly in May 2025.
According to the latest data provided by Cox Automotive, GMC had a 77 days supply during the month of May 2025, an increase from the 71 days supply figure recorded the month before. On the other hand, inventory dropped from May 2024’s 82 days supply.
As a reminder, the industry sees a 60 days supply as optimal for offering consumers choice while not overloading dealers with units that might linger on their lots and require hefty incentives to move out.
Among GM brands, GMC dealer inventory ranks second. Chevy has the lowest with a 65 days supply, while Buick dealers have a 78 days supply and Cadillac vehicle selection is the most plentiful at an 87 days supply. Meanwhile, the industry average stands at 70 days, up from a 66 days supply in April 2025.
Comparing Q1 sales to current available in-stock and in-transit GMC vehicles across U.S. dealerships, the GMC Yukon and the GMC Savana have the lowest inventory levels among the brand’s lineup. The GMC Hummer EV and the GMC Sierra EV currently have the highest estimated inventory levels.
Cox Automotive stated that there were 2.47 million new vehicles in inventory across U.S. dealers on June 2nd, 2025, compared to 2.49 million units on May 1st, a 0.8-percent decrease. Inventory is also down 14.5 percent compared to June 3rd, 2024. The analysis also mentions that showroom traffic peaked in mid-April, but has slowed down to more seasonal norms since, possibly indicating that consumers are turning back to a “more-measured car buying approach.”
Lastly, the average listing price for new vehicles at the end of May was $48,883, a 3.2-percent increase compared to the end of May 2024. However, the GMC brand’s average transaction price decreased slightly in May 2025 compared to the same period in 2024, reaching $65,913.

It doesn’t help when the dealership refuses to negotiate at all on the price.
