They sold me an 2007 Tahoe that had major problems with it. It wasn't serviced before we bought it, and they financed it with the worst financial institution ever.....Ally. Now I'm upside down on the vehicle......I ought to drive it to their front door and leave it.......I will never go back to Patterson Nissan or any of the Patterson's......period!!!!!!!
