Low inventories and supply issues continue to impact vehicle sales, but it appears the supply chain disruption bottom is in.
This graph shows actual sales from the BEA (Blue), and Wards forecast for December (Red).
The Wards forecast of 12.7 million SAAR, would be down about 1% from last month, and down 22% from a year ago (sales were solid in December 2020, as sales recovered from the depths of the pandemic, and weren't yet impacted by supply chain issues).
