buying a car

I absolutely HATE buying a new car. It is my least favorite thing to do. This time I am buying a "pre-owned" car. It is a 2007 model. You would think I was attempting to buy the Taj Mahal. They tag-teamed me. They added in hidden costs that they didn't explain - talked about items as if they were throwing them in for free when they weren't - tried to double back on things they offered me ... then when I tried to go out the door, the big dog appeared and asked for a dollar figure that I could live with. I low-balled it - he balked - I walked. I drove home. Within five minutes of walking in the door, the phone rang and they met me half way. I told the salesman that I needed to talk to my "fiance" and to call me in 30 minutes. He did. I said a figure that was between my lowball and the figure they had just offered. Now I am waiting for him to call me back. In some ways this is fun. In other ways it is just annoying. They just called. They offered a little bit higher than my offer. I suppose I have to let them win something. I told him I would be over in about 45 minutes. If I get over there and they screw around with me, I will walk away again.
