Hertz will list its used car inventory on Amazon Autos, starting with four cities before expanding to all 45 of the company's sales locations.

Hertz Car Sales has partnered with Amazon Autos to sell its used vehicles. It's the first fleet dealer to use the online car sales platform.

The partnership launched this week in Houston, Dallas, Los Angeles and Seattle, with plans to expand nationwide. It lets customers browse Hertz Car Sales’ inventory with Amazon’s shopping capabilities. Customers who buy online can pick up their vehicles within three days at a local Hertz Car Sales location.
