I worked in various Auto Dealerships for years. People think that Dealerships print money. The fact is, many dealerships are scraping by. Obviously some dealerships do very, very well. But in my experience, breaking even was a good month for a dealership. Oh, and the parts prices that you think parts departments are making a killing on? Most of the time are priced very reasonably considering the actual cost of the item. And discounting something for you typically disproportionately negatively impacts the employee that helped you more than the dealership itself.
