I always bought Chevy's until this year when I finally bought my beautiful CTD. Being a General Motors Employee, I had always been loyal and get GM's at a reduced price.
I won't pretend to know all the dealer jargon, and I also won't drive 200 miles to get a truck $500 cheaper, but I can tell you with 19 brand new vehicles purchased in three different countries, I have yet to have a dealer salesman at GM live up to his/her committments. Same thing now, if not worse at Dodge. Whether this be as simple as a free oil change, or floor mats, they always seem to go back on what they promised. You don't have to look very far in this website to find bad experiences. I know dealers have families to feed, but the fact is most of my bad experiences have nothing to do with price negotiation!!!!!
There are some exceptions, but I feel that I have had enough buying experience to say the vast majority of dealer sales people only enjoy helping their dealerships, and see themselves in the business of deceiving, and in many cases trained by their dealers to maximize money, not customer satisfaction.
The service personnel I have dealt with at GM and Dodge have been completely clueless, just last week they drove my CTD out on the lot and handed me the keys but the plug in the rear end cover was missing! Don't ever let a dealership tell you they have a good service dept. Request letters, references, meet the manager. . is he/she in on Saturday? Words are cheap... especially at a car dealership.
My advice: You will meet these 'shady' dealer personnel with each brand and each city, buy locally to make sure your tax dollars go to your schools and roads.
Sorry for being so wordy.
