I have been on this Forum for a long time and it would be news to me and several others that dealers are not allowed to post. Through the years there have been many dealers and dealership employees who have contributed a great amount of knowledge. They are though prohibited from posting to publicize their own business as are other commercial enterprises.
As a retired dealer myself, I can certainly appreciate the overwhelming circumstance of dealing with a professional whose stated objective is to sell you an expensive vehicle at the highest price possible. On the other hand, it can also be somewhat frustrating to deal with professionals in other fields whose primary purpose is to make money from the lack of knowledge of the user of their services.
It is always offensive to a group of people to be "despised" because of what they are rather than who they are. People are people...some good and some bad. You can hate the process without condemning everyone involved.
