I've found that I usually get a really low mileage car set aside for me. At one location with out an EA/ES they just pointed to the lot and asked "Which one do you want?" I thought that was pretty cool.
National also seemed to go the extra mile even as a regular Emerald member before I got bumped up to EE with all my travel this year.
And while HNL doesn't have the regular EA/ES, they do have a selection, you just have to go to a booth in the lot (not inside) and they ask which car you want from the mini EA/ES. They can't leave the keys in the cars since there is no exit gate. The staff there is always really friendly do I don't mind going to the booth in the lot at all, plus they give you a bottle of water. ^
