Confidentiality...

I remember the old adage that if you want to hold your parts manager responsible for the inventory, you shouldn't have a key to the department as the dealer!

Well, if you are attempting to sell your dealership and you want confidentiality, don't tell anyone; factory, dealer friends, attorney, cpa, until you have your Asset Purchase Agreement.

Use a trustworthy dealership broker who always uses a Confidentiality Agreement and one that does a proper job vetting candidates.
