What features do you want when you rent a car?

When I rent a car I obviously want it to be reliable. Beyond that, I like to have a CD player, although it isn''t strictly necessary. A working air conditioning system is a must. A GPS can be helpful, but I don''t want to have to pay extra for it. Power locks and remote entry are pluses because of safety concerns. Power windows are luxuries, but once again not mandatory since I rarely roll down the windows. I like the car to start with a full tank of gas. With gas prices rising so dramatically, this can be a nice gesture by the company that makes me more likely to rent from the company again.
