Next Monday at PHX, a four-day rental is pricing out at $788!
Fortunately, I made my reservation for $39/day a few weeks ago... I suspect it'll be like when I was there on 10/13, where the EA/ES was virtually empty (although the ES did have a convertable, which I couldn't use) and I had to go take an Impala off of the regular Full-size lot and be thrilled with it.
