Knowing what a car buys and sells for at wholesale and trying to figure out how the dealer makes their money is irrelevant to you. I've given you the best advice there is right now. You are overpaying and there is no way to avoid it, unless you have a trade. Then the dealer will overpay for your trade and you'll overpay for their car. When the marker goes back to normal, new and used prices, and trade values, will all drop.
