Now I want to know how much I could get out of it selling it in the paper or on craigslist. If I sold them on craigslist or in the paper how would I go about doing so?

I am not much of a person to trust someone so how can I make sure I get my money?

What is the normal process?

I read that people have had problems on craigslist like they show up to buy the car and the "buyer" jumps in it and takes off. I'm not sure of the answer to this question, but you ay want to consider seeing what you'd get on trade-in instead.
