Of all of General Motors’ U.S.-market brands, Buick has consistently posted higher days supply levels as of late. In fact, back in December 2022, the Tri-Shield brand had a days supply of more than 140, while November 2023 saw inventory levels hit a 107 days supply. Now, Buick inventory levels once again came in much higher than the industry average in December 2023.
According to a report from Cox Automotive, Buick inventory levels stood at 106 days of supply as of December 2023. This means that at the current sales pace, there is currently enough inventory on dealership lots to last for 106 days. In comparison to the rest of General Motors’ U.S.-market brands, Buick was ranked on top as Cadillac, GMC, and Chevy stood at 52, 68, 70 days supply, respectively, while the industry average was 70 days of supply.
It’s worth noting that these figures are related to the U.S. market. In addition, a 60 days supply mark is considered optimal across the automotive industry.
This is an interesting development when considering that General Motors has been actively taking steps to reduce its surplus inventory across all its U.S. brands. While most facilities were closed towards the end of the 2023 calendar year in observance of the holidays, the Detroit-based automaker also closed many plants for an extra week due to various maintenance projects.
Of course, while GM’s intention may not have been to lower supply levels, this decreased production output has the potential to help reduce supply figures moving through January 2024 and beyond.
As background, this study was based on the daily sales rate for the most recent 30-day period – which in this case ended on January 1st, 2024. Over this timeframe, December 2023 sales jumped 13 percent on a year-over-year basis for a total sales pace of 15.8 million units.
