When Pop bought his 2012 GMC 4WD he traded in his '99 GMC 4WD. That truck had 287K on it and still ran beautifully. The truck was not perfect but it still brought top dollar at trade in.
No vehicle with 287,000 miles brings in "top dollar" at trade in.
Some people will do anything for an argument.
They gave Dad more for his trade in than the KBB retail listing for excellent condition. Before you start telling me how they got it back by charging more for the new truck, they did not. Of the three dealerships we dealt with, two of the three offered us above KBB retail excellent condition, but they all wanted the same money for the new truck.
We all have our own definition of "Top Dollar". When a dealership offers more than the KBB trade in value and goes above retail excellent, that fits my definition.
