The average auto loan had a rate of 5.75% last month, reaching levels not seen since 2009 according to Edmunds. The annual percentage rate (APR) for new vehicles averaged 5.04% in May 2017 and 4.17% in May 2013.

But the spike in interest rates has yet to discourage car shoppers. Edmunds analysts said the prospect of greater rates later in the year is driving consumers to dealerships.

“Since interest rates have been creeping up all year, shoppers are likely thinking it’s better to buy now before rates get any higher,” said Jeremy Acevedo, manager of industry analysis at Edmunds. “However, this is likely a temporary pull-ahead effect, and could come back to bite automakers later in the year.”

Automakers sold 4.7% more vehicles in May and registered a seasonally adjusted annual rate (SAAR) of 16.91 million vehicles, up from 16.79 million a year ago. Sales gains were led by SUVs and pickup trucks, with Fiat Chrysler sales rising 11% on strong demand for Jeep vehicles. Ford F-Series truck sales rose to their highest May total since 2000.
