Cars can be sold as in stock, whilst they are in stock at a holding port or a PDI centre.  Many Dealers do not have the storage capacity to hold hundreds of cars with their showrooms or compounds.  When a vehicle is customer allocated, arrangements will then be made for the vehicle to undergo the PDI or be delivered to the Dealership for this process to be carried out.  More often than not, cars are stored with their protective film still attached, this is to protect the vehicle against the elements of the weather where they’re being stored.
