Wards Auto estimates sales of 13.31 million SAAR in December 2022 (Seasonally Adjusted Annual Rate), down 5.9% from the November sales rate, and up 4.7% from December 2021.
This graph shows light vehicle sales since 2006 from the BEA (blue) and Wards Auto's estimate for December (red).
The impact of COVID-19 was significant, and April 2020 was the worst month. After April 2020, sales increased, and were close to sales in 2019 (the year before the pandemic). However, sales decreased late last year due to supply issues. It appears the "supply chain bottom" was in September 2021.
