There is a significant variance in prices based on the dealer.
I understand these dealers have significant overhead (in fact, I frankly have no idea how any of them actually stay in business from a financial perspective), however, keeping one price on a vehicle that has been in stock is not a wise financial move.
In my business, there are situations where I have to make an educated decision with my clients to accept an offer of settlement rather than wait and wait for a potential better outcome that may or may not ever come--in the form of a jury verdict.
