Amazon began selling new cars late last year through an arrangement with Korean automaker Hyundai Motor, but consumers still must use a Hyundai dealer to complete the sale. Amazon is also recruiting car dealers to list their used vehicles, including those designated as certified preowned, on Amazon Autos.

Hertz Global Holdings stock jumped Wednesday after the car-rental company announced it plans to sell cars on Amazon.com. Hertz shares added 6%, closing at $5.51, while the S&P 500 fell 0.2% and the Dow Jones Industrial Average rose less than 0.

The partnership gives Hertz, known for its car rentals, more visibility and a potential profit boost for its auto sales business.
