In my experience with the same dealer for 9.5 years, I do see a lot of new faces now and then. The salesman I dealt with last was excellent from the beginning, then there was the financing guy. He tried to stick me with a 4.5% rate after I told I have a credit union I deal with. I had to ask for his manager before I could use my credit union's 2.2% rate.
The crew at this dealer's Quick Change oil change was a joke, they definitely didn't respect people's cars. Oily hand prints all over everything, rude, lazy, it was scary knowing they were working on your $70000 vehicle. finally they closed it and moved oil changes and services to the main service center.
