I am planning to buy a new car soon and was referred to an Aggie salesman who I have been working with. I am planning to finance the car, and I wondered, is the salesman affected by whether or not I finance at the dealership or independently? Or do they not care how I pay for the car as long as they make the sale? If I financed with the dealership initially but then refinanced with a bank or credit union, does that screw the salesman in some way? If I can secure a lower rate outside of the dealership and present that to them, any chance they will match it? I obviously want to do whatever is in my best interest financially, but I also want to make sure I'm not being discourteous to a fellow Aggie who has been very helpful.
