Well you have to see it from their perspective. They probably have every kid wanting to take a joy ride in the car with no intentions of buying it so they want to see how serious you are and whether you even qualify to finance it. It also has a lot to do with the way you present yourself. Be mature and respectful. Research the car before you go up there and once they see that you know what you're talking about then they will take you more serious. Don't immediately ask to take it on a test drive either.
