I'm pretty sure that it wasn't the sales person, because we also had to deal with his boss, who was the biggest @#%$ I've ever had the displeasure of dealing with. At the final signing, I requested them to remove their name plate cover from my car. He gave me some story about how important it was to keep it on, because if I get stuck or break down on the side of the road one day, somebody who brought the car from them would stop to help just we got our cars from the same place.
Then he admitted that if he was in my shoes he would not stop to help him. I got home and took them off anyway. That's way I have a cell phone and AAA.
