And now news of userd car prices coming down and rental firms buying fewer new cars to replace their older models implies things could get worse before they get better.

This piece of a Wall Street Journal article by Mike Colias and Adrienne Roberts highlights that rental company CEOs are getting nervous about the auto market.

Enterprise, one of the leading car-rental firms, reduced its vehicle purchases in the first half of the year compared with 2016, said Kurt Kohler, a senior executive in charge of the rental company’s fleet acquisition.
