When I was porter/detailer at the local Honda dealer, I made it a point to idle the cars I moved for 10-20 minutes to put a charge in the batteries. I also drove the cars I touched with respect - not like an idiot. Sometimes, with a car that had a dead battery and if the service department wasn’t using it, I’d hook up our “fancy” Midtronics GR-8 to the battery and let it charge in an empty service bay. If a car was low on gas, I’d ask the sales managers or service manager for a gas tag. Chevron station was a mile down the road. $10 was plenty for moving the car and test drives.
All new cars will have some mileage from train. /ship to truck on its way to the dealer’s lot and then for PDI. All the OEMs want the PDI done, and do reimburse the dealerships for it. Else, if a PDI was never performed, some warranty work could be denied. A PDI then was to install the fuse for the rest of the systems to work(for shipping only essential systems are powered), initialize the TPMS, run the engine until the fans cycle, install anything loose in the trunk(front plate mount, wheel covers, anything of that sort)
