If you live in "El Campo" and have purchased a vehicle in Spain, does the address on you registration documents agree with your postal address.  The address is copied from your Padron and used by the seller to register the vehicle.  If this is not your postal address and you incur a fine, it will be sent to the address on the Padron (which probably doesn't exist) and you will then be fined further amounts because you didn't respond (as you couldn't as you didn't receive the summons).  This probably also affect your BASE invoices.
