I agree that it is based on the manager. Fortunately, they seem to recognize their high volume customer and try to accommodate requests. That being said, I don't expect a Tahoe with a midsize rental every week, but I think they try to honor specific requests like having a car equipped with bluetooth. This usually equates to a decently equipped car.

Here are my experiences so far for mid-size (corporate) rentals:
- Nissan Rogue SUV (2x)
- Chevy Tahoe LT
- Chevy Malibu LTZ
- Dodge Ram 1500 Quad
- Hyundai Tucson
- Chevy Equinox
- Dodge Avenger
- Dodge Durango Limited

Favorites: Durango and Tahoe
Least Favorites: Rogue and Avenger

Great experience so far, big thumbs up.
