Hi,
One thing that I forgot to mention was that as with most legalities there are normally always loopholes
‘Legally you are entitled to drive a foreign-registration vehicle in Spain for six months a year. Your car can remain here permanently, but must be garaged and off the road for six months. You should also remember that if your car is not legal, you have no insurance cover, whilst your car should be insured in the country it is registered in.
So as I mentioned before if you have not informed your insurance company about your extended stay and if you should have the bad luck of being involved in an accident then you can be guaranteed that your insurance company will ‘back pedal the quickest that you have ever seen’.
