I rented a car today for a trip my wife & I are taking in August. I used Kayak to find the car, which came from Enterprise. I went to Enterprise's web site to see if the deal was better and they claim no cars are available at that location to rent. But Kayak, via Priceline, rented me a car from Enterprise. I've used Kayak before and never had a problem with not getting a car but this leaves me puzzled. Does Priceline pre-reserve cars somehow?
