I requested a different car after being given a car that had a stench of cigarette smoke. Five minutes before I was told that I had a choice, but when I requested a change - "there is nothing available" ... you have to go back to the place that I originally checked in at the airport. Persons name was Elizabeth. I said that I had been offered a different car 5 minutes ago. After insisting - I received a car that was sitting there. It had scratches and a 1/4 tank instead of the full tank it was supposed to have, but it was better than the other car.
The key to this complaint is that Elizabeth - when told about the cigarettes smell - said under her breath and then very clearly audible "I don't care.". I said that it was clear that she did not care. Pathetic.
