They will always give you the lowest of the low trade-in/buy.
They were going to give me $1500 for my 94 Nissan pickup a couple years ago. I sold it for $3500.
I recently went in to see what the bottom of the barrel was for my 97 Pthfinder. They offered me $8600. They're sellin comparable vehicles on their lot for $12,900.
Forget it. It's a good base point to start your own private sale or negotiate a trade at another dealer, and thats about it.
All IMO, of course.
