I would take your disclosure and point out the "tricks" the other dealers are playing and place this information into a informative semi professional transparent video you can send to your customers. Of course the video would have to be engaging enough to keep the customer watching but during this time you would be educating the customer on what to look for and how to compare pricing / apples to apples.
Place this video on a landing page within dealer website.
Got it.. btw.. nice off day today. I love blizzards on Saturday.
