Dealer offered me $4,500 for my 2005 Dodge Magnum RT with 87k on it. I said no thanks, and I sold my car outright myself 2 days later for $9,000. So In reality I should consider this another $4,500 to the good minus the $247.50 in extra sales tax it cost me. I could look back at all my papers, but I bought a 18 Limited 302A, 4x4, tow pac, Led lights, 360 cam, rear buckets, platinum white, for $16k under the window sticker list price. In the end that's over $20K less than it would of cost me to order a 19 and pay list price and take the bath on trading my car. Oh, I paid $75 for an online car ad, so you can deduct that too! I just found the best prices I could online and took the price to my local dealer and told them if they can get close to this that I'll buy it from them. 2 days later they located my vehicle out of state and dealer traded it and Brought it home for me and I wrote them a check and drove it home!
Usually the Dealer makes more on your trade than they do on the new unit. I rarely trade anything unless its value is too high to make it realistic to have someone buy it outright from me.
