We picked up a SUV (Buick Rendevouz (sp/) on 4/24 in the morning on the EA aisle. However, when we returned the car, normally I would just take the receipt and go. I had the car reserved for $162 or so for the entire stay. This time, I happen to look at the receipt the checker handed me and it showed over $770!!!! I had to go to the National booth and ask them to correct it and was told that the system overrode my rate because I had a SUV (reserved an intermediate size car). They corrected my rate for me. Make sure your receipt shows the correct rate before you walk away.
