I used to work in a bodyshop and probably a quarter of the work through the place were brand-new cars damaged in transit. Depends on the amount of damage but I’m with Jack, it’s unlikely to be a complete new door – a door skin or a repair is more likely unless it was severely damaged in which case I’d be paying close attenti0n to the hinges and locking pins etc, basically anywhere the door physically attaches to the car when closed.
