The 05 Vette I have has it and CPages2 is right, its more of a novelty than anything else. Once I tossed the key/rfid ring on the floor instead of putting it in my pocket and forgot it and accidentally locked the key inside the car. Had to leave the car where it was at and go home for the spare key. After about the 30th time you start it with the pushbutton, you will wonder why you spent the money and time for something that adds nothing to the car.
