Auffenberg Ford O'Fallon

We are new to the area and have been looking to purchase a vehicle. Initially we looked at purchasing a used car. We set up an appointment and when we arrived, we found the person our appointment was with went home for the day. Approximately a month later, we went to the Ford dealership to purchase a new car that was advertised with a rebate and 0 % financing. We were informed that the dealership would not allow us to have the rebate and the financing. The ad did not state this... Two weeks later, the same car advertised with the rebate (or) financing. We secured our loan and went down to purchase the car only to find out that they would not give us the advertised rebate if we financed it through someone else. I would never recommend Auffenburg to anyone and I will never purchase a vehicle through them. They do not honor what they advertise.
