From WardsAuto: U.S. Forecast: October Auto Sales Rate Flat with Prior-Year
A WardsAuto forecast calls for U.S. automakers to deliver 1.31 million light vehicles in October. A daily sales rate of 52,579 units over 25 days is nearly equivalent to like-2016’s 52,584 units for 26 days.
…
The report puts the seasonally adjusted annual rate of sales for October at 17.55 million units, behind year-ago’s 17.80 million and prior-month’s 18.48 million mark.
emphasis added
Sales had been below 17 million SAAR for six consecutive months, until September, when sales spiked due to buying following Hurricane Harvey. Sales in October were probably also elevated due to the hurricanes.
