Typical BS dealership. They sent me a letter indicating that they needed used cars the year and make of my current car. It said if you bring it in, they would pay up to 120% of black book value. I went into the dealership and as soon as I told them I wasn't interested in buying a new car from them if they bought my car, they told me the trade in manager was not in so they would have to call me with their offer. Guess what, never heard back from them.
I decided to call them several days later and spoke with the manager. I explained what happened and he said he would look into it and get back with me. He called and offered me several thousand dollars less than the black book value and my car is in excellent shape. He did say they could give me a little more if I was interested in buying a new car. I realize they have to make money so I wasn't completely surprised. However, don't fall for their BS offers, the only thing they are interested in is getting you in and buying a new vehicle.
