I just picked up a Chevy Equinox Sport with XM, leather... I had that same vehicle in Denver and really enjoyed it so I grabbed it again. My first choice at LAS was a loaded Volvo S40, but it smelled so bad of cigarette smoke that I left it. The rest of cars on EA were - Sebring, G6, minivans of various makes, a few new Highlanders, a Kia SUV and I think I spotted a Dodge Nitro/Jeep Liberty.
ES had about 8 Cadillac SRX, some new Malibus, Impalas, and one Nissan Maxima or Altima.
In all, not a bad selection, but I was the only one picking a car up at 6 a.m. I suspect it would clear out after more flights start coming in.
