With a midsize SUV reservation, picking up at about 4:00 PM on a Saturday, was offered a Nissan Rogue, Nissan Pathfinder, or Kia Sorrento. Opted for the Rogue, which turned out to be a 2011 model with about 13,500 miles on the odometer.
As I walked out to the Rogue, I didn't see anything particularly interesting parked in any of National's spaces.
I'd originally made the reservation for a 6:00 PM pickup Friday, but called the National counter at about 1:30 PM Friday to change the time (couldn't change on the website, since the contract had already been printed). When I picked up the car Saturday, the counter agent (not the person I'd spoken to Friday) noted that my rental contract had never been changed and mildly chastised me, saying something to the effect of "You should have told them to make sure the contract was changed." That left a bit of a sour taste in my mouth, because I thought that would have been implied if someone's calling to delay their pickup by 22 hours.
At any rate, he did manage to give me the same rate on the new contract, so there's not really much of a complaint to be made here.
