Pros: Good ad, good price
They let me know they could not do it fairly promptly but I relied upon the ads in making some last minute plans
Cons: I made a reservation with Budget and they called and told me there were no cars availalble.
Did the same thing with Avis thru Kayak, made a reservation and they called to tell me know no cars were availalbe.
Had to totally change plans and delayed my short trip by a day.
