Ain't that the God's honest truth?!
We rented from Enterprise last Nov and got a Ford Flex (they only came out that summer) so it couldn't be that old. The one we got from Cape Caneveral rental location was an 08. Can't remember whether it was a Jeep or Nissan or what? But it was newer. One thing I like about Enterprise is that more often than not, we have gotten at least one (and sometimes two) level upgrades at no add'l cost. I just had a rental from them here at home while I was having my Flex repaired (hit a deer

) and I got a Nissan rogue (sp?) and it was newer 08 and was in great shape. Off of the top of my head I cannot think of any bad experiences I have had w/ Enterprise's rentals.
Interesting.... while I am not doubting you. We had nothing but Wonderful experiences w/ Enterprise here in MD and at both WDW (Marriott, I believe) and Cape Canaveral. Marriott office gave us a double upgrade for FREE!

They were very accomodating. As a matter of fact, I don't think they could have been any more accomodating.
Well I, personally, have never (and I've rented from them over 10 times now) had a car that is more than a year to year and a half old. All of the ones I have gotten have had under 20K on them. Can't speak for others' experiences, but I highly recommend them.
