I generally hate treating anyone like a bad person but I figured out about 15 years ago that car dealers are only in it to extract as much money out of you as possible and there's no need to treat them as nice people. I've had success with my last few trucks emailing a dealer when I see the truck in stock that I want, saying "Attached please see pictures of my trade in, here's the VIN, here's the mileage. Please tell me the exact amount I will need to bring with me to your dealership in a cashier's check to get the new truck. I will only reply to one more email with a yes / no response. I will also not do any sort of credit check at your dealership so know that going in. I will walk away if your finance person claims that I have to do one."
