The dealer does have to pay three or four man hours of labor for a PDI - $300-500 lost opportunity time for that/those employees to be working on a rig for a paying customer.
Every good PDI I've heard of was with a shop person - not a service manager, salesman or such.
We even ask the service manager about something after the last PDI because the shop person didn't know how it worked. The service manager looked at the rig, went out on the lot and looked at some other rigs by the same manufacturer - can back and said he had no idea - he had never see that item before - and of our rig and the six on the lot - four had the item we had, and three did not. It took him an hour on the phone with the factory to find someone who knew the answer.
