smart dealerships near me (San Jose, CA)

My experience with this dealer was the worse I have ever had. They told me I needed to come down to their dealership soon for the car, it’s a 4hr drive for me. I made an appointment for the next day. During the day before, I spoke to the salesman, setting up the sale, financing etc. He stopped contacting me around 4pm, I called him right before they closed at 8pm. That is when he told me the car that he spent all day preparing to sell to me was sold to another person. He also said a manager would call me that night and no one called till the next morning. The manager was very understanding and that experience was better. However after my experience with the salesman I would never buy a car from Mercedes Benz San Jose ever. I had never been so disrespected and disappointed while making a deal before. If he had simply told me someone else was in the process of buying, I would have said ok and moved on. Instead he set up financing with me, but the other parties just went through first.
