Wow, never again.
I waited in line over an hour to pick up the car. No one behind the counter seemed concerned with the 20+ person wait. When I finally got to the counter the clerk was friendly, and was trying to chat me up, but all I wanted to do was get outta there. Sure the car was cheap, but it wasn't worth the time spent standing in line.
When the car was returned had to wait for over 30 min to catch the shuttle back to the main rental facility, to catch the bus back to the airport.
The Versa was clean and the AC worked well enough.
