I did not buy anything, but when I visited the dealership, I found the employees to be friendly and helpful. The salesman I worked with was Mark and he was very nice and responsive. Despite the fact, the dealership was extremely busy that day, Mark came and met me within a few minutes of my arrival he was able to juggle several customers at once and allow me to test drive the vehicle I was seriously looking at.
