I have been thinking of trading in my fist. The dealer I was looking at a car from Had edmunds trade in guide on site so looked at what said car was worth. My fist came it at like 9k trade in value using it and it really made me sick. Kbb was like 11,300 and nada 12,400 or so. In past I always averaged nada and kbb when negotiating trade in.This edmunds seems like a real joke. Is it a realible source? Or are they just out to be in favor of dealers?
