I don't know that it is appropriate for a drive, exactly, but Anne Hathaway reading the Wizard of Oz is one of the best audio books I've ever listened to, period.

My only hesitation for a drive is that you might get too comfortable. It is like a loving mother reading to you while you're comfy in bed. She does different voices for the main characters, so she has her scarecrow voice and her Wicked Witch of the West voice. It is super underrated as I have never really heard anyone talk about it.
