I work for Crown and we till do trade in on trucks/suv's, we don't lowball to hell, but we don't offer generously either. The reasons dealers lowball on big vehicles, is because its based off auction prices. If they offer youu 6 grand for an explorer, its because thats what we can get for it at auction if we can't sell it on the lot. And with the market the way it is, no ones bidding on those vehicles, meaning we don't have any security in it, meaning we offer even lower..same as most dealerships.
