The Manheim Used Vehicle Value Index stood at 209.4 in October, down 2.3% from September. The index is down 4% from a year ago. These wholesale prices filter into the retail side of the market with a slight lag.  

"October revealed some not-so-spooky price moves, namely a reversal of the gains that were seen during the prior two months," said Chris Frey, senior manager of Economic and Industry Insights for Cox Automotive.

Frey continued, "This confirms the caution that was mentioned last month The UAW strike, avoiding one action that could have led to higher wholesale prices. October's price decline is eerily similar to last October's 2.2% drop, and this was not unexpected as the market remains balanced. Wholesale vehicle values typically experience some modest increases during the holiday season, and with two months remaining, we could see some upward price movements." 

Charles Schwab Chief Investment Strategist Liz Ann Sonders was the first to point out on social media platform X that the Manheim price index has "extended its maximum drawdown to -18%, which is largest in index's history." 

X user CarDealershipGuy said the "strikes [UAW] are over" and "now back to reality." He said used car demand is waning.
