What do I need as a NEW DRIVER seeking Car Insurance?

I am nineteen years old, and I just got my license in July. My dad just gave me a car, it's used and is six years old. It has over 100,000 miles on it. I need insurance for it, but I don't know what I should have as a minimum. I don't want to pay more than 100 a month. I just need some ADVICE!
