Walked into the dealership and was immediately greeted by Matthew Smith. He listened to what we wanted and the process from start to finish was the best experience I have ever had at a dealership. We arrived at 4:30 pm test drives and locked in a vehicle, met with Bella in finance who was also great finding the best rate for us and we were all signed on our new Cadillac XT4 by 6:45 pm. I highly recommend this dealership if you are looking for a vehicle
