I always carry 2 different kinds of reading material. Usually a book and a magazine.

CD wallet full of my entire collection. I like singing in the car, no matter how goofy I must look.

Water bottle, for good urinary health, ladies.

A small makeup kit in a copper case that was a free gift from Clinique.

My purse with standard wallet, keys, sunglasses and my asthma inhaler which I only need when I don't have it on me.
