>Brad, I have walked in with printouts from KBB.com for each vehicle
(the trade-in AND the new/used vehicle). Initially I didn't show them to anyone until the runaround process began, but that's pretty good ammo for you, if you really want the other car.
Also, while you were in the glove box, did you think to copy down the previous owner's name and address, and/or any of the stations or dealers the car had been serviced by? I think I might just call and see what kind of work had been done previously. Sneaky, but perfectly legal, especially if they left that info in the vehicle.
