Expert Perspective — Jeremy Robb, Chief Economist, Cox Automotive
- July and early August witnessed stronger depreciation trends, but the decline slowed later in the month.
- Younger vehicles experienced more depreciation, while older, affordable models saw less drop, indicating a rising demand for economical used cars.
- Retail sales of used vehicles rose throughout August, contributing to decreased retail days’ supply, which fell to 44 days from July’s 46 days.
