The UAW strike loomed larger in the beginning of September.

The industry braced for potential repercussions, resulting in a deceleration in market depreciation, according to Black Book experts.

After the strike, auction conversion rates surged as buyers geared up for a possible inventory dip. While the depreciation rate slowed compared to the previous week, the weekly declines still surpass the usual seasonal fluctuations.

In mid-September, the UAW initiated their strike, auction activity saw an uptick toward the week's end.

The extent of the strike's impact on the used car market hinges on its duration. In 2019, during the last UAW strike, its brevity and an existing surplus of new inventory meant minimal impact on used values.

In contrast, the current scenario involves supply levels gradually returning to a "normal" state post-pandemic. Consequently, a prolonged strike might drive up used prices in the short term.

As for the last week in September, the UAW strike persisted and the market entered a phase of pricing stability.

Despite this, a noticeable surge in buyer interest at auctions is reflected in consistently rising conversion rates each week.
