Also... what car rental company would ever buy orange cars? That seems completely stupid, I have never had a rental car that wasn't black or grey.
I don't know how car rental works in the US, but reading this article it sure looks quite broken compared to the places I have rented cars (France, Japan, Taiwan).
But yes, we can choose the category. And you will get it unless they are out of cars for that category. An orange Dodge Nitro was considered an "upgrade" from what I reserved. One time though I had reserved a Camry and they were out so they upgraded me to a Prius instead. It was nice driving the car back to the airport after a week of driving and not having to fill up the gas tank all week.
them-> "Here are the keys to your Dodge Durango"
you-> "no, actually I reserved a 4-door sedan"
them-> "I know sir but we don't have any left"
you-> "huh? I reserved one. what does a reservation mean?"
them-> "it's subject to availability sir"
In other words, (like many restaurants, like many airlines, hotels, etc), you can "reserve" anything you like, it doesn't mean it has been set aside for you.

If you like them more power to you! I won't throw eggs at it or anything, promise. :) I would just never choose one for myself.
To reserve a car you like only to be given the car you despise is... disappointing.
Oh my god, the PT cruiser is my exact nightmare every time I rent a car, and it's happened to me toooo many times.
