What are the steps to buy a car? What questions do I need to ask and ensure I have no hidden fees, etc. with the car dealer?

I have not bought a car in a long time on my own (about 20 years ago) so I am skeptical and nervous about getting one now. I am a single woman and so I am nervous going into this again. I want to give as much a down payment as possible so as not to have to pay so much interest.

I bought a car, and it is a great car. Just too much technology for me.
