I reserved intermediate class in Phoenix last week and was given a Mitsubishi Lancer. Was very disappointed in the lack of amenities on this particular car, which may come with aux or bluetooth as an upgrade, but the car they gave me had none. I didn't even ask because I had figured that an ipod connection if not bluetooth would have been standard for this class which is why I paid for intermediate. Had to drive through mountains with only a spare CD on loop. Next time I rent from avis, I will know to insist upon a car with the aux connector option.
