there was a thread earlier .. i used them in march and had absolutely no probelems, new car ( ford windstar 4000 miles on clock ) friendly service and they accepted my german insurance for the rental. Had a great rate from orbitz for 129 USd a week for the minivan and glad i did use them !!
I can recommend them.. there seems to be some negative postings about them, most of them from people " that did hear from a friend... " thing....
They are onsite, they are cheap, car was fine.. what else would you like from a rental car company ??? Make sure you have your insurance certificate with you when renting !!
