This is what i keep in my car(It's over priced, but it's a decent kit. I won a GC to a local store, so that's why i picked it up).

nemesiss45's suggestions seem dead on. Whatever you get, just make sure you actually
KNOW HOW TO USE the items in there. I've seen lots of people get huge kits and never bother to learn basic first aid required to use them, like how to apply a a tourniquet.
