“The month of May saw a noticeable swing from beginning to end, and while overall depreciation finished at just 1.2%, the end of the month started to pick up steam,” said Anil Goyal, vice president of automotive valuation and analytics for Black Book. “We anticipate June will show the beginning of summer seasonal patterns, with many vehicles showing ‘no sales’ at auctions due to lower buyer demand.”
