Do not give into them. You are the one with the control. They are going to ask you, "how do you plan on paying the vehicle?" Tell them you first want to know what the lowest price is on the vehicle you want. If the price they give you is more than what you're willing to pay, ask them again if that is the lowest they can go. If they say yes, then tell them you are going to shop around. Don't tell them you are paying cash. Don't tell them how much you have because then they know how much they have to work with.
