Dealership sales of used vehicles were flat in December, while supply levels remain constrained among the most affordable models.

Driving the news: According to Cox Automotive, retail sales of used cars hit 1.4 million units last month.

  • That’s in line with November’s sales, ending a period of month-over-month growth. However, dealers sold 12% more than they did in December 2023.

  • December’s certified pre-owned (CPO) sales rose 4% from November but were lower by 4.9% compared to 2023 levels, driven by tight supplies of off-lease vehicles and trade-ins.

  • Used car listing prices were slightly higher on a monthly basis, hitting $25,271, but average listings are still down 3% from the previous year.

While affordability challenges will likely persist into this year, listings for top-selling used car brands (Ford, Chevrolet, Toyota, Honda, and Nissan) are currently 5% cheaper than December’s average. Targeting models from these automakers could provide some relief to customers.

Zooming in: While sales were in stasis after November, inventory is becoming more constrained, especially for cheaper models.

  • Days’ supply of used vehicles at the start of January was 48, up slightly from December but tight for the time of year, with past January levels typically above 50 days.

  • Used vehicles under $15,000 had only 37 days’ supply, 11 days below the overall industry average.

Looking ahead: Lower production between 2020 and 2024 continues to squeeze the supply of used vehicles from those model years.

  • This strain on inventory is likely to ramp up in 2025. Cars.com predicts dealers will see a 7% decline in supply levels for vehicles aged zero to six in the months ahead.

  • Despite inventory constraints, Cox Automotive still expects to see an increase in used car demand, forecasting a retail sales total of 20.1 million (up 1.2% from 2024).

  • However, with fewer off-lease vehicles returning to the market, dealers should expect CPO sales to shrink by about 1.6%.
