Ok, I'll respond, out of my cave for a second...
You're dealing with Budget rent a car. Lower your expectations, and then lower them another notch. Everytime you think you can rely on "something" (miles, promotion, etc.) they change the rulles, without telling you (or sometimes their non-corporate locations). So if you think you're goin' get them to adhere to some definition as to what constitutes a certain size of car, you're in dream land.
