the best way to combat sh*t house serivce and have been told by a person who owned a car dealership for well over 30yrs is before you leave ask to speak to deal principal tell him/her there service is rubbish and the salesman have no idea and then proceed to tell him you will take you business to another dealer. buy the car and go back to the dealer and give then a friendly wave. he said nothing hurts more then a simple sale.
