Linda, the very FIRST thing you need to do is to emotionally DETACH yourself from this truck. When you get emotionally attached to something, it's way too easy to pay too much. It's a business deal, pure and simple, nothing more...nothing less, and by your comments, you already own the truck from an emotional standpoint. I'm not trying to be harsh, I'm simply trying to help you spend the least amount of money and get not only a truck that you want, but also the best value for your money.
Another point that I disagree with in several posts are the references to KBB. Auto dealers almost exclusively use N.A.D.A. pricing for their ACTUAL numbers, the numbers that they need to use to make a profit.
And just so all of you know, I'm not concerned either about how much or how little a dealer makes on a deal. I'm there to buy the product they have for the very least amount of money that I have to spend to get what I want.
My current truck was purchased by me from a dealer that was six hours away from me. I told him (once we got the truck price down to an acceptable number) that I will not pay $599 for Doc fees. He told me that those numbers are set by the dealership and printed on the sales order and cannot be negotiated away. My response to him was that he should then deduct another $499 from the bottom line and name it whatever he wanted for additional discount. He didn't really want to do that and I told him that would be the only way I would make the drive over and complete the deal. The sales order showed that I paid a $599 Doc fee, but in reality, the extra $499 discount money caused it to be a $99 Doc fee, which I feel IS reasonable.
