I would temper your expectations on getting anything above autotrader which is the "black book" quote. The group Buy pricing is so aggressive that there is just not much room in the deal for them to pad your trade. Could you go get $5 k more for your trade from another dealer? Sure, but you'll then pay $5 k more for the new car. I'm not saying you can't try to maximize your trade, just don't expect them to be able to get to what you think it's worth.
Using KBB, autotrader, Nada, and Edmunds, I had a really good idea for what was reasonable for my trade. I went to another dealer that was more local to me and they offered me right around the average of all those sources (which for me was right around the 'good' value on KBB). I negotiated my trade value over the phone because 1) I didn't set my expectations too high and 2) I had a written quote from another dealer so Koons knew it had been looked at. When I showed up at Koons they assessed and confirmed my trade in and trade value.
As many have said, the group buy pricing (even with the lower trade in amount) was simply the best deal on a vehicle I've ever gotten. The experience at Koons (dealing with Nader in one email, two phone calls, and for about 2 hours total at the dealer) was the smoothest car buying experience I've ever had.
Good luck. I hope you get what you want, I'm just trying to let you know what my experience was.
