I reserved a Prius at PHL for Saturday. I don't ever want to own one (if a car doesn't have a manual transmission the way god intended, I ain't buying it

), but I figured if I'm going to be renting a car, and no reasonably priced rental cars are anything I actually want to drive, I might as well reserve a Prius so I can see what all the fuss is about since I've never driven one and the cost was only a few bucks more than the midsize and that should pay for itself in gas. Does that mean that the car is actually guaranteed? I've never seen car companies let you reserve a specific model like that. This was specifically a Prius - not a green collection or anything like that. And if they don't have any Priuses, what should I expect to get? Thanks
