I really do not understand the idea of never admitting fault and never saying "sorry". After 40 years in the business, was involved in many cases of vehicle damage. It does happen when moving motor vehicles around in tight spaces. You train your people that they are not going to be fired for the first happening but will be if they don't report it. As someone else said, the mark of the good dealer is how well you fix the problem and take care of repercussions. That includes an apology for the customer inconvenience.
