A foreign registered vehicle can only remain in Spain for 6 months for non residents or tourists. If the owner is deemed to be resident then the vehicle must be re-registered within 1 month of the owner becoming resident.
Traffico are regularly stopping UK registered vehicles and it would be prudent to carry ferry tickets, V5 (not copy), permission slip from owner and insurance for driver. Traffico can check MOT and Tax online.
To keep the UK registered vehicle legal you'll need to return it to the UK twice a year, one of these visits could incorporate the MOT (if required).
