Probably most of us that work in the sales department at a dealership would love to not have FRT/PDE, Air Tax, Gas Tax, etc., etc. listed out on a bill of sale. Our lives would be much easier if these charges were already included in the MSRP but that's not how the manufacturer or the government want it. They require that we list them out separately. We are invoiced by the manufacturer for the vehicle, freight, air tax, advertising, etc. They then tell us what to charge for each of these additional items on top of the price of the car. PDE is the inspection of the vehicle after it arrives to ensure that it is in proper working order and that all fluid levels are topped up. Like a safety certificate, it ensures that the vehicle is road worthy and has not sustained any damage and that everything is still good after the ship, rail and/or trucking process. If you've ever seen any of these guys load or unload vehicles from a railcar or truck, I'd think you might want someone to double check the vehicle! They also do things like install fuses, wheel covers, washer fluid, etc. which is not done on the production line.
