I found a 2006 Element EX-P with 72,000 miles for sale. It has new tires, front brakes and looks to be in pretty good shape in the photos. He is asking $15,900 but it isn't selling. I looked up KBB and came up with a value around $15,000. I sent him an e-mail saying that I wouldn't even go look at it unless the price was near KBB value. He responded a week later saying the lowest he would take would be $15,000. Is this a fair price for this Element?
