I just purchased my 38th vehicle. I decided not to go through the hassel of dealing with a salesman and shopped over the internet. I used the GM site and asked for a quote from three local dealers. I received a reply from two and the third was on vacation. I received a price under dealer cost. They gave me two different trucks to drive over the weekend and I bought one of them. It was painless. I would like to hear others good or bad experience.
