In my featured blog a week or so ago I warned dealers on allowing anyone to have access to your DMS system. In my blog I also added the FACTORY. Most dealers dont know that you can section out what you want to have vendors and the factory can have access to. In my opinion I would only allow the factory to the F and I section. This allows them to see what the dealer rdr'd on new sales. I would not allow them into service if at all possible. Reason: You the dealer collected all thos emails on all your customers that are bringing in there car for service. Without that information the factory cant cherry pick your best service profit customers and start sending them NEW car offers which as the factory normally does suggests you as the dealer to see BUT also lists dealers in your district.  Jim Ziegler has taken it to another level and dealers are seeing what and is happening with there data.
