October 2023 Market First

ZeroSum’s Take: What You Need to Know 

The bigger picture of the automotive industry landscape has a direct effect on how dealers should make their decisions and manage their businesses. The dynamics of a given dealer’s actions on issues such as pricing, inventory allocation, and marketing spend should look to the macro-trends that provide context for those actions.   

It is well understood that the last several years have been difficult to navigate, with multiple challenges to contend with. COVID, post-COVID recovery, chip shortages, broader supply chain issues, the UAW strike, and initial and accelerating inventory recovery are just some of the bigger events that have had a major impact on dealers across the country. The Market First report is designed to provide that bigger picture viewpoint and backdrop in which dealer decisions are made. 

This month’s report focuses on a continuing rise in new car inventory, which has been accompanied by a gradual drop in new car pricing as supply has continued to recover.  Meanwhile, on the used car front, inventory growth took a slight pause after eight months of continuous increases. Used car pricing continued to fall even with this month’s small dip in supply. 

In both cases, the longer term trends are pointing to an environment in which dealers are having to work harder to sell individual vehicles even as the rebound in supply provides them with more inventory to meet consumers’ needs. 

By the Numbers 

October’s new car inventory is rising, with EOM predicted to be 2,372,739.  

New car prices have dipped to $50,830, a decrease of -1.37% from September EOM, the third month in a row prices have dropped. 

Used vehicle inventory is predicted to be 2,060,971 at EOM. This is a slight decrease from 2,081,560,which was where inventory sat at the end of September - and used car prices have declined for the fifth month. 

October 2023, total EV supply has increased to 311,424, with all three categories - electric, gas/electric hybrid, and plug-in hybrid - increasing inventory.

New Vehicles Retail Outlook





October’s new car inventory is continuing to rise, with EOM predicted to be at 2,372,739.  

New car prices have dipped to 50,830, a decrease of -1.37% from September EOM. October marks the third month that new car prices have dropped. MSRP is, on average, $51,536, which widens the gap between MSRP and marketed price to $706.

ZeroSum can report that October EOM used vehicle inventory is predicted to be 2,060,971. This is a slight decrease from 2,081,560, where the inventory sat at the end of September. After the industry saw rapid increases in used inventory at the beginning of 2023, the past few months of small decreases appears to indicate that used car inventory could be leveling out.  

ZeroSum has reported that the price of used cars had decreased over the past four months, and October 2023 has kept up that trend and adds a fifth straight month. The average price of a used car is now $29,156, a -1.07% decrease from September EOM ($29,471). The decline in prices has generally coincided with the rebound in inventory as used cars have become less scarce. 

Electric Vehicles Retail Outlook

October 2023 total EV supply has increased to 311,424, with all three categories - electric, gas/electric hybrid, and plug-in hybrid - increasing in inventory. September’s total EV inventory was 286,799, so the U.S EV inventory has grown 8.59% from September to October 2023.  

After a small dip in pure electric inventory last month, October has shown an increase from 113,646 to 120,733, a MOM change of 6.24%. Gas/electric hybrid had a MOM change of 14.25%, with October inventory for that category now 111,480. The plug-in hybrid inventory for September is 79,211.
