US new and used car supplies are plummeting as consumers rush to buy before anticipated tariff-related price hikes. Cox Automotive reports new vehicle days' supply dropped from 91 to 70 days in March, while used vehicle supply fell to 39 days. This surge in sales, exceeding last year's pace by 22%, is causing concern about potential inventory shortages once tariff-free stock is depleted. Telemetry predicts significantly reduced annual vehicle sales due to increased production costs.
