Great car at a great price
Pros: Reserving through Kayak well in advance resulted in a highly competitive price for my 9-day rental. I received a clean Nissan Altima, which was ready when promised. During the trip the car sustained minor damage. When I returned the car the staff were courteous and efficient. While I won't know how the costs of repair will work out yet - the car and the staff were all great.
Cons: This rental was great. I only wish that Hertz, like Zipcar, would provide specific information on the car (make, model and features) and options before picking up the car.
