Jon was right on point.

Jon was right on point. He managed almost everything on the phone several days before I was able to travel to the dealership. He had the truck detailed and filled up with fuel before I got there. The paper signing took less than 15 minutes then Jon took the extra time to show me all of the new features. Very pleasant, friendly, and courteous dealership to purchase from. I highly recommend Vanguard and Jon!
