I usually rent 1-2 times a week. Usually in CLE, IAH, BWI, and EWR.

I can't remember the last time I did not find my car in the PC section and didn't get more than a one class upgrade. I usually reserve a mid-size and get a premium or H class. I like the G35 and after they moved it to H class, don't get it as often, but have been getting an Avalon or Kia. Sometimes I get a premium like a Buick La Sabre, or Grand Marquis. In those instances I usually go back and ask for something smaller. I haven't seen a Ford Taurus in a long time.

My coworkers who are #1 Gold, but have no status don't get any upgrades and their cars are in the normal section. After they added their car preference to their profiles though, they have consistently been getting what they requested in that class.

When reserving cars on "sold out" days, I was able to reserve a car on Hertz.com where my coworkers weren't able to.

I have never just shown up at the station without a reservation though. When arriving at an airport without a reservation, as soon as I land, I will usually call and the car has always been ready for me by the time I get to the rental station.

This winter in Cleveland, my car was always ready with the engine running and the heat on. That was very nice.
