Unlike in U.K. where one can drive to a previously arranged MOT appointment, in spain that is unlikely, depending on who one asks. Under U.K. law Mac you might be able to drive, starting the journey to an appointment, albeit in spain, to say a port of embarkation (an interesting legal point to argue) even so if one came by ship to say Santander, it would mean taking it on a truck to the ITV test. I would think driving through France would not be permitted either.
Probably not cost efficient
PS Maybe worth looking at, but probably not cost effective either. Register the car in U.K. and MOT it, drive it Spain and then register it in Spain
